feat(desktop): one browser session and extension system for every pane - #9523
Panes agents open now use the same session as every other browser pane (persist:browser), so they get the user's extensions, extension toolbar and logins.
The browser bridge no longer refuses the user's own panes: agents can list, drive, CDP-attach and wake any browser pane.
Why / Context
Extensions should work across every browser pane. #9221 put agent-opened panes in a separate persist:browser-agent session with no Web Store extensions, so sessions' browsers had no extensions and started signed out.
How It Works
Removed AGENT_BROWSER_PARTITION / PANE_PARTITIONS; webviews, UA setup, shims preload, internal extension load, downloads and clear-data use BROWSER_PARTITION only. The extension host already serves that session, so agent panes become extension tabs with no extra code.
The pane agent flag is gone: no pane acts differently based on who opened it. One hidden-webview eviction pool for every pane (agent use still counts as use), no openUrlAgent route param, and pane-layout snapshots drop browser.agent.
Bridge: removed isAgentPane and the 403 / CDP 1008 refusals. list includes every pane, and wakeBrowser rebuilds any unloaded browser pane, not only agent ones.
Cookies: the pane's CDP session refuses every cookie read/write command (Network.*Cookies, Storage.*Cookies, clearDataForOrigin with cookies, Cookie/Set-Cookie headers in Network/Fetch commands) and strips cookie headers and cookie lists from Network/Fetch events (cdp-cookie-guard.ts). import-login stays the only way to add cookies.
Agents may sign in with the user's password manager when asked (skill); /panes now requires a workspaceId.
Toolbar shows pinned extensions + Extensions menu on agent panes too.
Login-import dialog copy now says cookies go into the in-app browser (all 17 locales translated).
superset plugin's browser and panes skills no longer say user panes are off-limits; the safety section names password managers and autofilled passwords.
Manual QA Checklist
Install an extension in a user pane; superset browser open from an agent shows it in the agent pane's toolbar and it runs there
Agent pane is signed in to sites the user is signed in to
superset browser list shows user-opened panes; eval / screenshot / CDP work on them
An evicted pane (user or agent) is rebuilt on an agent command
Clear browsing data still works
Testing
bun run typecheck (desktop): clean
bun test on src/main/lib/browser, BrowserPane, and _authenticated/components: 701 pass, 0 fail (bridge tests updated: agents reach the user's pane; eviction wake works for a user pane)
bun run check:i18n, bun run check:plugins: pass
Not verified in the running app yet.
Known Limitations
The old persist:browser-agent data (including cookies imported into it before) stays on disk; nothing reads it anymore.
Risks / Rollout
Risk: security trade-off by design. CDP can no longer read or write cookies, but eval can still read document.cookie (non-HttpOnly only). Agents now act in the user's signed-in session next to their password manager, and eval/CDP could read an autofilled field. Only the skill's instructions guard against that.
Rollback: revert this PR; agent panes go back to the isolated session.
Summary by cubic
Every browser pane, user- or agent-opened, now runs in one shared persist:browser session, so agent-opened panes get the user's extensions, extension toolbar, and signed-in sessions instead of starting logged out.
Agents can list, drive, CDP-attach, and wake any browser pane; the pane agent flag and its separate hidden-webview eviction pool are gone. Pane listing now requires a workspaceId.
CDP can no longer read or write cookies: cookie commands are refused and cookie headers and lists are stripped from network events. import-login stays the only way to add cookies.
Clicking a pane's extension button makes that pane the active tab first, so popups act on the right pane; a newly registered pane no longer takes the active tab.
An extension's new tab never claims a pane a browser open request created, and a pane resolved through resolveOpenRequest is skipped by the extension's waiter.
The browser skill lets an agent sign in with the user's password manager when asked, as long as it never reads the filled value back; only those instructions guard against misuse.
The old persist:browser-agent data stays on disk but nothing reads it; revert this PR to restore the isolated session.
Written for commit 4da8c08. Summary will update on new commits.
Summary by CodeRabbit
New Features
Browser controls, extensions, and browser tools are available across workspace browser panes. Activating an extension selects the pane it applies to.
Browser panes share a signed-in session, making imported cookies, logins, and extensions available across panes.
Updates
Cookie-import notices and browser guidance describe the shared in-app browser and provide updated sign-in and sensitive-data guidance.
Browser tools block cookie access and changes, and remove cookie details from supported network information.
Clearing browsing data applies to the shared in-app browser session.
Panes an agent opened ran in a separate persist:browser-agent session with
none of the user's extensions or logins, and the bridge refused the user's
own panes. Every browser pane now runs in persist:browser: agent panes get
the user's extensions, extension toolbar and logins, and agents can list,
drive and wake any browser pane. The agent flag on a pane now only picks
its hidden-webview cap.
This drops the autofill isolation recorded in
plans/20261030-browser-pane-passkeys.md; the browser skill tells agents
never to read autofilled passwords or cookies.
Browser panes now share BROWSER_PARTITION, and the bridge lists and operates on workspace browser panes without agent-only restrictions. The change removes agent-pane metadata, adds CDP cookie-command refusals and event redaction, and updates pane controls, guidance, and translations.
Changes: Shared browser session and pane access
Layer / File(s)
Summary
Use one browser session across panes apps/desktop/src/shared/constants.ts, apps/desktop/src/renderer/.../BrowserPane/*, apps/desktop/src/renderer/.../useBrowserOpenRequests.ts, apps/desktop/src/renderer/.../usePaneLayoutRequests.ts, apps/desktop/src/renderer/.../persistBrowserPaneState/*, apps/desktop/src/main/lib/browser/pane-session.ts, apps/desktop/src/main/lib/browser/download-manager.ts, apps/desktop/src/main/lib/extensions/index.ts, apps/desktop/src/lib/trpc/routers/browser/browser.ts, packages/shared/src/pane-layout-ops.ts
Browser panes use BROWSER_PARTITION and no longer carry an agent flag. Session setup, download listeners, extension loading, and browsing-data clearing target the browser partition. Background opens, wake requests, and hidden-webview eviction no longer use agent-specific handling.
List and operate on workspace browser panes apps/desktop/src/main/lib/browser/browser-bridge.ts, apps/desktop/src/main/lib/browser/browser-bridge.test.ts
The bridge requires a nonempty workspaceId to list panes. It includes loaded and unloaded browser panes and removes agent-partition checks from pane operations and CDP connections. Tests cover access to loaded and unloaded panes.
Extension controls render for every pane. Extension activation selects the target pane. The skills and plan describe shared browser access and cookie-handling rules. Translations describe cookie import into the in-app browser.
CDP cookie protection
Layer / File(s)
Summary
Refuse cookie access and redact event data apps/desktop/src/main/lib/browser/cdp-cookie-guard.ts, apps/desktop/src/main/lib/browser/browser-manager.ts, apps/desktop/src/main/lib/browser/cdp-cookie-guard.test.ts
The browser manager refuses selected cookie-related CDP commands and redacts cookie data from selected network events. Tests cover refused and allowed inputs, and event redaction.
Shared browser access still carries unresolved workspace-isolation, login-import, and sensitive-data handling concerns. Extension tab selection can also diverge from the selected pane. Resolve or explicitly accept these issues before merging.

Explanation
The title "feat(desktop): one browser session and extension system for every pane" follows conventional commit format and matches the main change. The PR puts all browser panes, user- and agent-opened, into the shared persist:browser session, removes the agent pane flag and separate partition, and gives every pane the user's extensions and logins. The title captures the primary change. It is slightly broad because it omits the bridge, cookie guard, and pane-listing changes, but that is expected for a title.
Full details: Description check
Explanation
The description covers the required template sections. 'What & why' is present and explains the problem: agent panes used a separate session without extensions or logins, which is the #9221 regression. It does not link an issue, but it does reference the plan file. 'How I tested it' lists typecheck, test, and i18n/plugin checks and a manual QA checklist, and it states the changes were not verified in the running app. The checklist items are present, though the template's screenshot preference for user-visible changes is not addressed. The description also includes a security risk section and a rollback note beyond the template.

Review: minor issues. The code is clean and works live: agent and user panes share persist:browser, and eval, CDP and wake now work on a user pane. But it removes a deliberate security boundary with only skill prose in its place, and it leaves the old agent session's cookies behind.
apps/desktop/src/main/lib/browser/browser-bridge.ts:209 / :711: agents can now eval or attach CDP in the user's own panes, next to their password manager. The only guard is the skill text. Consider keeping the shared session but asking the user once before an agent drives a pane it did not open, or adding an opt-in setting.

Now that agent panes share the user's session, raw CDP could dump every
cookie, HttpOnly session tokens included, or plant new ones. The pane's
CDP session refuses the cookie commands (Network/Storage get, set, delete
and clear, clearDataForOrigin with cookies, Cookie or Set-Cookie headers
in Network and Fetch commands) and strips cookie headers and cookie lists
from Network and Fetch events. Importing logins stays the only way to add
cookies.

Persist navigation from detached guests to the owning layout.
If agent navigation arrives before a detached guest registers, wakeBrowser reuses the guest without replacing its callback. The callback writes to an unsubscribed workspace store, so eviction or restart can restore the old URL. Ensure detached guests persist navigation to the owning layout.

Update the navigation persistence callback around persistBrowserPaneState so
detached guests write to their owning layout’s store, including when navigation
arrives before guest registration and the guest is reused. Do not retain a
callback bound to the unsubscribed workspace store.

When imported cookies overlap existing cookies, the import can replace logins across the shared browser. Other panes may switch accounts or lose their sessions. Add this warning to both the consent dialog and the import-login guidance before users approve the import.

Update the import consent dialog and the import-login guidance to warn that
imported cookies may replace existing logins in the shared browser, affecting
sessions in other panes; show the warning before users approve the import.

A popup such as Dark Reader's asks Chrome for the active tab. That was the
pane registered last or last clicked inside, so after switching workspace,
or after an agent opened a pane anywhere, the popup acted on another pane
(it showed "about:" and "This page is protected by browser"). A click on a
pane's extension button now selects that pane first, and a newly registered
pane no longer takes the active tab.
…en made
With one session for every pane, the session no longer told an extension's
new tab apart from a pane `superset browser open` made in the same workspace
at the same moment, so the extension could claim and drive that pane. Panes
named through resolveOpenRequest are now skipped by the extension's waiter.
Browser skill: scratch pages open in a new tab, a password is filled only on
the origin the user named, and import-login says it replaces existing logins.

persist:browser), so they get the user's extensions, extension toolbar and logins.Why / Context
Extensions should work across every browser pane. #9221 put agent-opened panes in a separate
persist:browser-agentsession with no Web Store extensions, so sessions' browsers had no extensions and started signed out.How It Works
AGENT_BROWSER_PARTITION/PANE_PARTITIONS; webviews, UA setup, shims preload, internal extension load, downloads and clear-data useBROWSER_PARTITIONonly. The extension host already serves that session, so agent panes become extension tabs with no extra code.agentflag is gone: no pane acts differently based on who opened it. One hidden-webview eviction pool for every pane (agent use still counts as use), noopenUrlAgentroute param, and pane-layout snapshots dropbrowser.agent.isAgentPaneand the 403 / CDP 1008 refusals.listincludes every pane, andwakeBrowserrebuilds any unloaded browser pane, not only agent ones.Network.*Cookies,Storage.*Cookies,clearDataForOriginwith cookies, Cookie/Set-Cookie headers in Network/Fetch commands) and strips cookie headers and cookie lists from Network/Fetch events (cdp-cookie-guard.ts).import-loginstays the only way to add cookies./panesnow requires aworkspaceId.supersetplugin's browser and panes skills no longer say user panes are off-limits; the safety section names password managers and autofilled passwords.Manual QA Checklist

persist:browser-agentdata (including cookies imported into it before) stays on disk; nothing reads it anymore.Risks / Rollout
evalcan still readdocument.cookie(non-HttpOnly only). Agents now act in the user's signed-in session next to their password manager, andeval/CDP could read an autofilled field. Only the skill's instructions guard against that.Summary by cubic
Every browser pane, user- or agent-opened, now runs in one shared
persist:browsersession, so agent-opened panes get the user's extensions, extension toolbar, and signed-in sessions instead of starting logged out.agentflag and its separate hidden-webview eviction pool are gone.
