feat(desktop): storage.sync, onInstalled and lasting context menus for browser extensions - #9330
Stacked on #9329. Makes Vimium and Google Translate work, and reconciles that with the file check.
Why
Vimium is broken: Electron 44's chrome.storage.sync exists, but every call fails. The extension package hid that by aliasing sync to local, so keys collided, and content scripts still got the error.
Google Translate has no right-click item:runtime.onInstalled never fires in Electron, and Translate creates the item only there. Context menus also lived in memory only.
Changes
storage.sync: it is its own area, stored in storage.local under a prefix so the two can't collide. It covers every get form, quotas, both callback and promise forms, onChanged with area "sync", and a read-only managed.
Content scripts and in-iframe extension pages get no preload, so the shim is written into the extension folder as superset-storage-shim.js and added first to the manifest's content scripts and to each page.
The file check accepts exactly that change: the shim file must match the app's copy byte for byte, and a shim tag anywhere else, or any other edit, still counts as tampering.
chrome.extension.inIncognitoContext is false where missing. Vimium's find mode needs it.
runtime.onInstalled: the app fires it with reason install, update or chrome_update. The worker confirms once its listeners ran, and only then is the version recorded, so a worker that stops early gets the event again.
Context menus are saved per extension and version, restored on load, and dropped on update or remove. contextMenus.update now works.
Removing a turned-off extension also clears its DNR rules and saved state.
Patch notes in patches/README.md now cover this patch's native messaging change.
Testing
Unit:
the storage areas stay apart
shim placement
the file check across install → shim → restart → tamper
onInstalled re-delivery after a worker stops early
menus restored per version
Dev app:
Vimium shows link hints on f
all 8 extensions load across restarts with the shim in place, and none are turned off
Google Translate's item was created and saved after the recovery below
Recovery for profiles from intermediate builds
If a Translate install shows no menu item, set installed.<id> to null in browser-extension-state.json with the app closed.
Known gaps
Vimium settings saved under the old sync→local alias look unset.
In-iframe extension pages still lack the package's other APIs.
Summary by cubic
Makes Vimium and Google Translate work in the browser pane: chrome.storage.sync no longer fails, runtime.onInstalled fires, and right-click menu items survive restarts.
chrome.storage.sync is its own area, stored in storage.local under a prefix so the two can't collide; it covers Chrome's quota, callback and promise forms, and onChanged with area "sync". managed is a read-only empty area.
Content scripts and extension pages in website iframes get no preload, so the shim is written into the extension folder as superset-storage-shim.js, first in each content script and page. The shim also gives content scripts chrome.extension.inIncognitoContext false, which Vimium's find mode reads.
The file check accepts exactly these changes: the shim must match the app's copy byte for byte, and any other edit still turns the extension off.
The app fires runtime.onInstalled with reason install, update, or chrome_update. The worker asks for the event, runs a snapshot of its listeners, and confirms only once they ran, so a failed ask, listeners that left early, or a worker that stopped gets the event again. Unreadable state is never overwritten, and corrupt state is moved aside.
Context menus are saved per extension and version, restored on load, and dropped on update or remove. contextMenus.update works instead of being a no-op.
Removing a turned-off extension clears its DNR rules and saved state even when clearing its data fails.
The package's runtime.connectNative and runtime.sendNativeMessage are dropped; the app's native messaging path is the only one left.
Recovery
For profiles from intermediate builds: if Google Translate has no menu item, set installed.<id> to null in browser-extension-state.json with the app closed.
Known gaps
Vimium settings saved under the old sync→local alias look unset.
Extension pages in website iframes still lack the package's other APIs.

Summary by CodeRabbit
New Features
Improved browser-extension compatibility for local, sync, and managed storage areas.
Extension install and update events now report the appropriate lifecycle details. Context-menu items can be restored after a restart when the extension version is unchanged.
Bug Fixes
Extension removal now completes cleanup and updates the app even when storage or rule cleanup fails.
Browser-extension APIs enforce permissions more consistently, including access to tab and cookie information.
Changes
Native-messaging APIs are no longer available to extensions.
- Agent panes no longer show the puzzle button or pinned icons: they run
in the agent session, which has no extensions.
- An extension whose context-menu code throws no longer stops the page's
right-click menu from opening.
- Space pins a row in the extensions menu only when the user is not
typing a name to jump to a row, so "dark reader" searches instead of
pinning.
- CLI install and remove questions close as a no when the caller hangs
up or 50 s pass. Over the relay the CLI gives up at 65 s, and a later
yes used to install or remove after the CLI reported failure. The
bridge answers 408 and says nothing changed.
- Bridge errors keep their meaning through host-service: 403 FORBIDDEN,
408 TIMEOUT, 503 PRECONDITION_FAILED, instead of all BAD_REQUEST.
- Removing before the extension host started threw nothing and reported
success; it now fails. Installing the ID of the app's bundled
extension says it is built in instead of "already installed".
- Routes say whether the extension must be installed, instead of
comparing req.path.
…inned
- The install, update and permission questions list each kind of access
on its own bulleted line.
- Chrome's wording for declarativeNetRequest ("Block content on any
page"), debugger, downloads, bookmarks, geolocation, topSites and
desktopCapture, plus "Run scripts you add on websites" for
userScripts, instead of raw API names after "Use more browser
features".
- A new extension is not pinned to the toolbar, as in Chrome. It is in
the Extensions menu, and the user pins it there or with
`superset browser extensions pin`.
Full-colour logos filled the 14px box the line icons use and looked
heavier. They draw at 12px with the same 22px button, and the count
badge uses the small size so it no longer covers the icon.
Extensions in the browser pane can now call chrome.runtime.connectNative
and sendNativeMessage, which password managers use to reach their
desktop app (1Password's com.1password.1password host).
electron-chrome-extensions already had a native messaging path, but it
read each stdout chunk as exactly one message, counted UTF-16 units as
bytes, ran hosts without a cwd, never set runtime.lastError, never
stopped sendNativeMessage hosts and left hosts running on unload or
quit. The patch now removes it, and the app serves native messaging
itself:
- Lookup as in Chrome: <host>.json in Chrome's and Chromium's
NativeMessagingHosts folders (system-level first) plus the app's own
userData/NativeMessagingHosts; the Windows registry on win32. The
host name, "stdio" type, absolute path and exact
chrome-extension://<id>/ allowed_origins are validated, and only an
extension that declares "nativeMessaging" may connect.
- Launch as in Chrome: the main process spawns the host with the
extension's origin as its argument and the host's folder as cwd
(cmd.exe with --parent-window on Windows), with native-endian length
framing, Chrome's 1 MB host limit and 64 MiB extension limit.
- Ports report host exit, start failure and I/O errors through
onDisconnect with Chrome's runtime.lastError text. sendNativeMessage
closes after the first reply. Hosts are stopped when the port
disconnects, the worker stops, the frame navigates or closes, the
extension unloads, or the app quits. An open port keeps the service
worker alive, as in Chrome.
- The preload shim adds the APIs only in extension contexts that
declare the permission, and the main process takes the extension id
from the sender's frame URL or worker scope, never from the message.
Website frames and the CDP bridge cannot reach it.
1Password still decides whether to trust the app: its helper verifies
the code signature of the browser that launches it. A user must add the
signed app from /Applications under 1Password > Settings > Browser >
Add Browser.
… before loading
Installs and updates verify the CRX, but at start the app loaded each
unpacked folder as is. A file changed after install (malware, another
tool) then ran with the extension's full access, for example inside a
password manager.
Web Store CRXs carry _metadata/verified_contents.json: a SHA-256 tree
hash of every file, signed by the Web Store (RS256, Chromium's
kWebstoreSignaturesPublicKey). electron-chrome-web-store keeps it when it
unpacks. Before loading, each extension is now checked like Chrome's
content verifier: the Web Store signature, then the tree hash (4096-byte
blocks, branch factor 128) of every file. A file not in the list, a
missing file, a link or a missing signature also fails. No trust on
first use is needed for these files.
Chrome skips manifest.json, but here it decides permissions and scripts.
The package rewrites it to add `key`, so it no longer matches its signed
hash. The CRX verifier now saves the CRX's own manifest.json to
<userData>/browser-extension-manifests/<id>/<version>.json at install and
update. At load the saved copy must match the signed hash, and the file on
disk must be exactly the package's rewrite of it, with a key whose ID is
the signed item_id.
Extensions installed before this change have no saved manifest. On the
first start with this change, their manifest.json is trusted once (trust
on first use) and its SHA-256 is saved; all other files are still checked
against the signed hashes. A marker then closes this path, so a missing
saved manifest later fails the check. The next update replaces the
trusted hash with the signed original.
An extension that fails the check is not loaded. It is logged and moved to
<userData>/browser-extensions-turned-off, so the store page's install path
cannot load the old folder. The extensions menu lists it as "Turned off
because its files changed", with reinstall (a fresh, verified download
that keeps its local data) and remove. Startup loading now runs before
the store API is registered and no longer uses the package's loader.
1Password 8.12 (1006 files, 44 MB) checks in about 30 ms with a warm
disk cache. The check runs in the existing async extension startup, not
on the window's critical path.
Electron 44 exposes Chromium's chrome.declarativeNetRequest bindings to
extensions (CoreExtensionsBrowserAPIProvider registers them), but its own
request proxy (api::WebRequest via ProxyingURLLoaderFactory) never consults
the DNR ruleset manager, and Electron's docs list no DNR support. So uBO
Lite and other MV3 blockers install, show their UI, and block nothing.
Main now owns each extension's rules and enforces them on the
persist:browser session only:
- The extension shim replaces chrome.declarativeNetRequest in extension
pages and service workers with an IPC-backed version (Chrome's constants
and enums kept) that reaches main over the same channels as offscreen.
- Static rulesets load from the manifest's rule_resources, honoring
enabled flags, updateEnabledRulesets and updateStaticRules (reset on
extension update, as in Chrome). Dynamic rules persist to
userData/browser-extension-rules/<id>.json; session rules stay in memory.
- The engine follows Chrome's evaluation: highest priority wins, ties go
allow > allowAllRequests > block > upgradeScheme > redirect, then
session > dynamic > static; across extensions a block wins, then the
most recently loaded extension's redirect. allowAllRequests is derived
from the committed URLs of the request's frame chain. modifyHeaders
applies above the extension's allow priority. Redirect and modifyHeaders
need host access; block/allow/upgrade do not unless the extension only
holds declarativeNetRequestWithHostAccess.
- Rules are indexed by request domain, then by the rarest whole URL token
of the urlFilter, then by initiator domain, so a request visits only
candidate rules. 40k rules plus a 30k-domain rule index in ~30 ms and
evaluate in ~2-3 µs per request in bun.
Electron keeps one webRequest listener per event per session, and the
pane session already had the Google sign-in header hook. A small
WebRequestHub now composes hooks per session, and the header hooks are
registered only while some extension has modifyHeaders rules.
tldts supplies the public suffix list for domainType (first/third party).
…emove questions
Native questions use the store's icon for Web Store installs and the
extension's largest manifest icon otherwise; the in-app Remove dialog
shows the same icon as the menu row.
…er turn off for missing data
In the real app every installed extension was turned off with "it has no
Web Store signed hashes". Electron's ElectronExtensionLoader::LoadExtension
(shell/browser/extensions/electron_extension_loader.cc) deletes the
extension's _metadata folder before every load, so verified_contents.json
is gone after the first start. The bun tests never called Electron's
loadExtension and could not see this.
The CRX verifier now saves the CRX's verified_contents.json next to its
original manifest.json, in
<userData>/browser-extension-manifests/<id>/<version>.json, and the check
uses that copy. _metadata in the extension folder is ignored.
An extension with no record, or a record that is malformed or does not
verify, is never turned off: it loads, and the SHA-256 of each of its files
is recorded (trust on first use) and checked on later starts. This covers
every install made before this change; the next update replaces the
record with the signed one. A read error also loads the extension and
logs. Only a file that differs from a usable record (changed, added,
missing, or a link) keeps an extension from loading and moves it to
browser-extensions-turned-off. The marker that closed trust on first use
is removed.
The tests now use a fake session that deletes _metadata on load, as
Electron does.
…pane extensions
Vimium broke because Electron 44 has a chrome.storage.sync object whose
every call fails with '"sync" is not available in this instance of
Chrome' (managed too). electron-chrome-extensions hid this in extension
pages and service workers by making sync the same object as local, so
keys collided and changes said "local"; content scripts, where Vimium
loads its settings, still got the error.
chrome.storage.sync is now its own area, as in Chrome without sign-in:
kept in storage.local under a key prefix that local's get, getKeys,
getBytesInUse, clear and onChanged never show, with Chrome's sync quota,
callback and promise forms, and onChanged / sync.onChanged events with
area "sync". managed is an empty read-only area. The shim reaches every
context of the extension: the session preload covers pages and service
workers, and because no preload reaches content scripts or extension
pages in a website's iframe (Vimium's HUD and Vomnibar), each load of a
Web Store extension writes the shim into its folder as the first
content script and the first script of each page. The patch stops the
package's preload from replacing chrome.storage.
Google Translate's menu item never appeared: it makes it in
runtime.onInstalled, which Electron never fires, and the package keeps
menu items in memory only. The app now keeps, per extension, the version
onInstalled last fired for and the menu items, in
browser-extension-state.json. A worker's onInstalled shim asks for the
event once its listeners are added and gets "install", "update" with
previousVersion, or nothing; extensions installed before this file
existed get "chrome_update" once, so their menus come back. Items are
restored when the extension loads, dropped when its version changes
(the update fires onInstalled again) and when it is removed. The patch
announces each create/update/remove/removeAll, adds
restoreContextMenuItems, and makes contextMenus.update a real handler
with a permission rule instead of a no-op.
Checked against Electron 44.10.0 with the patched package, outside the
app: the real Vimium 2.4.2 shows link hints with no sync error in its
content scripts or HUD, and the real Google Translate 2.0.18 has its
"translate" item after install and after a restart.
… changes
The storage shim writes superset-storage-shim.js into a Web Store
extension's folder, puts it first in the manifest's content scripts and
adds a script tag to each page. The integrity check from
browser-extension-integrity counted each of those as tampering, so every
extension would be turned off on the next start.
No session preload reaches content scripts (registerPreloadScript takes
only frame and service-worker), and Chromium reads content scripts and
manifest.json from disk, so the folder has to change. Intercepting
chrome-extension:// with protocol.handle does reach pages, but it would
mean serving every extension resource ourselves. The check now knows the
exact changes instead:
- superset-storage-shim.js must equal the app's own bytes. The app
writes its current copy over it before the check, so an app update
that changes the shim does not turn extensions off.
- A page with the tag is compared with the tag taken out, only if
putting it back gives the same bytes; a tag anywhere else stays and
the hash fails.
- manifest.json must be the original (signed, or recorded on first use)
or exactly shimManifestText of it. Trusted records now keep the
manifest text; a record from before this keeps hashes only, and gains
the text the first time the manifest matches them.
Any other change still turns the extension off. Pages are rewritten as
latin1 so their bytes survive in any encoding, and the manifest is
written with two-space indent like the web store package.
Content scripts also get chrome.extension.inIncognitoContext (false)
when Electron leaves chrome.extension out; Vimium's find mode reads it.
…ion-all-v2
Combines storage.sync, runtime.onInstalled and lasting context menus with
native messaging, declarativeNetRequest and the review fixes.
- removeBrowserExtension deletes the extension's DNR rules and forgets its
lifecycle state.
- extension-host starts DNR enforcement, then lifecycle tracking and the
storage shim injection.
- The preload shim takes takeInstalledDetails after the DNR args. It sets up
runtime.onInstalled before the native messaging block, which returns early
for extensions without nativeMessaging.
- electron-chrome-extensions patch regenerated with bun patch from both
sides' package sources: no native messaging handlers or preload entries,
no storage override, real contextMenus.update, context-menus-changed and
restoreContextMenuItems.
…eners ran
The app recorded an extension's version as soon as its service worker
asked for the onInstalled event. Anything that went wrong after the
answer, such as the worker stopping before its listeners ran, or a run
whose menu items were not saved, then lost the event for good. Google
Translate makes its right-click item only in onInstalled, so a dev
profile that went through intermediate builds kept "installed" at
2.0.18 with no saved menu, and the item never came back.
The worker now asks for what is pending, runs its listeners, and then
confirms with the version it was given. The app records the version
only on that confirmation, so a worker that stops first gets the event
again at its next start. A listener that throws still counts as
delivered, as in Chrome, so an extension is not sent install over and
over.
Checked in Electron 44.10.0 with the real Google Translate 2.0.18 from
an existing install (no state file): chrome_update, item made and saved,
restored on restart with no second event; and with the app quitting
before the worker ran, then the worker asleep at the next start: the
event comes at that start and the item is saved.
The changes update extension API permissions and context-menu handling, add Chrome storage compatibility, and introduce persistent extension lifecycle state. Integrity checks account for injected shim files. Extension removal now performs final cleanup and state updates after removal.
Changes: Browser extension support
Layer / File(s)
Summary
Extension API permission controls patches/electron-chrome-extensions@4.10.0.patch
The CommonJS and ESM builds add API permission checks and result filtering, track runtime and active-tab grants, and update tab, window, and cookie behavior.
Context-menu and preload support patches/electron-chrome-extensions@4.10.0.patch, apps/desktop/src/main/lib/browser/extension-host/electron-chrome-extensions-patch.test.ts, patches/README.md
Context-menu changes emit events, contextMenus.update is implemented, and saved items can be restored without an event. The patch removes native-messaging handlers and updates preload behavior and documentation.
A storage shim provides local, sync, and managed areas. The extension host adds the shim to extension files, and the preload installs it in extension pages. Tests cover storage operations and file injection.
Integrity checks verify injected shim files separately and compare extension pages after removing the shim. The loader refreshes shim files before verification. Tests cover shim persistence and extension ID discovery.
The host persists extension versions and context-menu items. Service workers request pending install details through IPC, and lifecycle tracking restores menus and records delivered events.
Removal cleanup now invokes the removal callback, unpins the extension, and notifies listeners even if storage clearing or rule deletion fails. The host removes the extension from persisted state.

Batch menu-state writes, because each create rewrites the full state file synchronously.
Each contextMenus.create emits the extension's full item list. The listener calls state.saveMenus synchronously, and save() serializes and writes the entire state file. Nothing caps the item count, so N creates can cost roughly O(N²) serialization on the main process. Coalesce these writes, for example with a short debounce that flushes on quit, and keep the temp-file rename.

A script that an extension injects with chrome.scripting.executeScript does not receive the storage shim. Its storage.sync calls can reach Electron's unavailable native area. The shim reaches only manifest content_scripts and extension pages, and the preload shim returns outside chrome-extension: pages.

This can occur when: A native runtime supplies a non-configurable lastError property when a quota or managed-write call fails.

windows and rejecting writes that exceed either limit. Preserve the existing
per-item byte, total-byte, and item-count checks; if those rate limits cannot be
enforced reliably, remove them from the advertised sync API instead.
- Around line 258-259: Update the storage.local set and remove handlers to
reject keys with the reserved sync prefix before calling callNative; check every
key in set items and handle both string and array inputs to remove. Leave other
keys on the existing native-storage path.

MAX_ITEMS using stale snapshots; enforce the item-count quota in the
main-process operation that spans contexts and commits the write, using its
current state atomically with the write. Keep the existing per-item and
total-byte quota checks intact, and do not rely on a per-context queue.
- Around line 180-188: Update sync.get and the existing storage migration flow

chains.
- Around line 233-235: Update both CJS and ESM copies of hostPermissionMatches
so explicit host permissions match by scheme and host without comparing the
pattern path to the target URL; retain the existing pattern-shape validation

Seed the first-run baseline with turned-off extensions.
On a first run, createExtensionState marks only the install-root extensions as installed before. Turned-off extensions live in browser-extensions-turned-off, so they are not marked. Re-enabling one then sends reason: "install" instead of chrome_update. Include the turned-off folder IDs in the installedBefore callback passed from extension-host.ts, alongside the install-root IDs.

Skip the shim tag only when the page was shimmed.
readOriginal removes the first SHIM_TAG from every .html or .htm file, even when the app did not insert that tag. An extension whose signed original page already contains <script src="/superset-storage-shim.js"></script> immediately after its <head>, <html>, or doctype opening fails the signed hash check. checkExtensionFiles then throws ExtensionIntegrityError, and loadUserExtensions moves the extension to turnedOffPath.
Compare the recomputed hash with the signed original, and accept the raw bytes when they match. The same change is needed in verifyTrustedFiles.

Validate restored menu items before they are saved as restorable.
readState keeps any record in items. create rejects an item without a truthy title unless its type is separator, but restore skips that check. A damaged or hand-edited state file with items: [{}] therefore restores an item with no id and an empty label.

If writing or renaming the state file fails, markInstalledDelivered still updates memory and the IPC handler returns success. After restart, the old version is loaded and the same update can fire again. Failed menu saves also disappear. Keep the version or menu change pending until persistence succeeds.

Reconcile saved extension state against installed extensions.
When an extension directory is deleted outside removeBrowserExtension, its entry in browser-extension-state.json stays. A later install of the same ID and version gets no runtime.onInstalled and has its old context menu items restored. Drop state for IDs that are neither installed nor turned off, at startup.

Serialize sync writes so the quota check sees the latest state.
Concurrent sync.set calls each read the area before either native write commits. Each call passes the MAX_ITEMS check against the same snapshot, so the area can exceed 512 items.

Ignore the path in host-permission matching for tabs.insertCSS.
hostPermissionMatches compares the pattern's path with the page path. Chrome ignores the path of an explicit host permission. For https://example.com/foo/*, the guard denies tabs.insertCSS on https://example.com/bar with an error, although the extension has access to that host.
Suggested fix
Apply this change to both copies of hostPermissionMatches in the patch file (the CJS copy near line 64 and the ESM copy near line 627). The pathPattern capture becomes unused, so it is removed. The regex still requires a path, which keeps the pattern shape validation.

Update both CJS and ESM copies of hostPermissionMatches so explicit host
permissions match by scheme and host without comparing the pattern path to the
target URL; retain the existing pattern-shape validation that requires a path,
and remove the now-unused path capture.

Reject parentId values that create a cycle in contextMenus.update.
The new update handler stores parentId without checking the parent chain. A cyclic chain never reaches the top level of the menu build, so the menu silently omits those items and their children. Walk the parent chain before storing, and throw when it reaches menuItemId.

Update the contextMenus.update handler to walk the proposed parent’s chain
before storing parentId; throw if the chain reaches menuItemId, and leave the
existing parent assignment unchanged for non-cyclic chains.

Migrate settings written through the former storage.sync alias.
The removed preload factory mapped storage.sync to storage.local, so existing sync settings were stored under unprefixed local keys. The new sync.get reads only prefixed keys and does not fall back to those existing values. Without a migration, upgraded extensions can receive no saved value and may use their defaults.

Update sync.get and the existing storage migration flow to recover settings
previously written through the former storage.sync alias under unprefixed local
keys; establish how to read those legacy local values and migrate them to the
prefixed sync keys, while preserving already-present sync values.

Stacked on #9329. Makes Vimium and Google Translate work, and reconciles that with the file check.
Why
chrome.storage.syncexists, but every call fails. The extension package hid that by aliasingsynctolocal, so keys collided, and content scripts still got the error.runtime.onInstallednever fires in Electron, and Translate creates the item only there. Context menus also lived in memory only.Changes
storage.sync: it is its own area, stored instorage.localunder a prefix so the two can't collide. It covers everygetform, quotas, both callback and promise forms,onChangedwith area "sync", and a read-onlymanaged.superset-storage-shim.jsand added first to the manifest's content scripts and to each page.chrome.extension.inIncognitoContextisfalsewhere missing. Vimium's find mode needs it.runtime.onInstalled: the app fires it with reason install, update or chrome_update. The worker confirms once its listeners ran, and only then is the version recorded, so a worker that stops early gets the event again.contextMenus.updatenow works.patches/README.mdnow cover this patch's native messaging change.Testing

Makes Vimium and Google Translate work in the browser pane:
chrome.storage.syncno longer fails,runtime.onInstalledfires, and right-click menu items survive restarts.chrome.storage.syncis its own area, stored instorage.localunder a prefix so the two can't collide; it covers Chrome's quota, callback and promise forms, andonChangedwith area "sync".managedis a read-only empty area.superset-storage-shim.js, first in each content script and page. The shim also gives content scriptschrome.extension.inIncognitoContextfalse, which Vimium's find mode reads.runtime.onInstalledwith reason install, update, or chrome_update. The worker asks for the event, runs a snapshot of its listeners, and confirms only once they ran, so a failed ask, listeners that left early, or a worker that stopped gets the event again. Unreadable state is never overwritten, and corrupt state is moved aside.contextMenus.updateworks instead of being a no-op.runtime.connectNativeandruntime.sendNativeMessageare dropped; the app's native messaging path is the only one left.Recovery
