Fix passive Firefox attachment and automate npm/AMO releases

[SunkenInTime]

Codex could not attach to Firefox/Zen tabs because the CDP adapter rejected Page.setLifecycleEventsEnabled. This implements lifecycle subscriptions, consistent document loader IDs, and detach cleanup. Regression coverage reproduces the original exception on 1.4.10; an isolated headless Zen test verifies real lifecycle events and that background-tab attachment preserves the foreground tab.

Prepares synchronized version 1.4.11 and Windows/macOS/Linux verification and release artifacts. Tagged releases now check Mozilla author credentials, publish GitHub assets before npm, verify public npm installation on macOS/Linux, then submit the existing listed Firefox add-on with matching source and reviewer notes. npm retains tokenless OIDC publishing. Manual dispatch can either build candidates or check AMO credentials without publishing; neither mode publishes, even when dispatched against a tag. Mozilla approval may remain pending after CI submission.

Validation: full npm test, npm installer tests, Rust tests, isolated Zen lifecycle smoke test, workflow actionlint, and web-ext lint (0 errors, 0 notices, 72 existing warnings). AMO checker tests cover JWT signing, pagination, missing credentials, ownership mismatch, and HTTP failures. Real AMO authentication and add-on author access passed in CI run 34521313242. Both repository secrets are configured; no version has been published or submitted.

The full signed-in Codex transport remains a documented final release check. Network-idle notifications and replay of lifecycle events predating subscription are not synthesized. See RELEASE_1.4.11.md for credentials and release steps.

@greptileai Please review the lifecycle attachment fix and release preparation at 4f1fd76. The isolated Zen smoke test passes without activating the target tab.

📝 Walkthrough

Walkthrough

The extension adds Firefox CDP lifecycle-event support with stable loader IDs and cleanup. Tests cover lifecycle delivery and background-tab preservation. Version 1.4.11 metadata, verification workflows, publication gating, and release documentation are updated.

Changes

Firefox lifecycle compatibility release

Layer / File(s)	Summary
Lifecycle event runtime extension/firefox-compat.js	Adds per-frame lifecycle state, stable loader IDs, Page.setLifecycleEventsEnabled, navigation lifecycle events, and detach or tab-removal cleanup.
Lifecycle regression and live validation tests/test-firefox-compat.mjs, tests/test-firefox-lifecycle-live.mjs	Tests lifecycle event ordering, loader ID consistency, subscription cleanup, frame-tree updates, and inactive-tab preservation.
Cross-platform verification and publication gating .github/workflows/verify.yml, .github/workflows/release.yml	Adds multi-platform npm and Rust verification. Restricts npm publication to tag pushes after the publish job completes.
Version and release documentation version.json, extension/manifest.json, native-host/Cargo.toml, package.json, npm/package.json, CHANGELOG.md, PORT_STATUS.md, README.md, RELEASE_1.4.11.md	Aligns version values at 1.4.11 and documents lifecycle compatibility, smoke testing, verification, and release procedures.

Confidence Score: 5/5

The verified lifecycle, loader-ID, AMO credential-routing, and release-publication behaviors are safe to merge.

What we checked:

• Lifecycle subscription survives detach: Detaching a child target removes that frame's lifecycle subscription and session mapping. Lifecycle delivery resolves the current session and returns without emitting when its subscription is absent.
• AMO JWT follows untrusted pagination: Each pagination URL must remain on the AMO origin and exact add-on-list endpoint before an authorization-bearing request is sent. Redirects are disabled for that authenticated request.
• Manual dispatch publishes artifacts: GitHub release, npm publication, and AMO submission require both a push event and a tag reference. A manual dispatch has the workflow_dispatch event name and skips all three jobs.
• Document loader IDs diverge: Document requests reserve a per-frame loader ID, and a committed navigation adopts that pending value into the frame map. Lifecycle and frame-navigation events read the same committed per-frame value.
• An attached child session received init, DOMContentLoaded, and load lifecycle events; after detachment, the same session received zero further lifecycle events; the focused compatibility suite, syntax check, and whitespace check completed successfully; a real-browser variant could not run because Firefox was unavailable.
• The AMO pagination URL guard runs before the request that carries the JWT authorization header; existing mocked unit coverage passed; a focused malicious-pagination mock rejected an attacker-controlled next URL before issuing a request to it.
• The release, npm publication, and AMO submission jobs each require both a push event and a tag reference; a simulated manual dispatch at a tag skipped all publication jobs; the workflow diff and current job guards confirm that only pushed tags can publish artifacts.

Summary

• This update improves Firefox and Zen CDP lifecycle compatibility, aligns release components on version 1.4.11, and adds AMO publishing safeguards. Focused checks confirmed that detached child sessions stop receiving lifecycle events, navigation protocol events retain one loader ID, AMO credentials are not sent to untrusted pagination URLs, and manually dispatched tag runs cannot publish release artifacts.

@greptileai Addressed the loader-ID finding: document requests reserve the committed loader, redirects and responses retain request-scoped IDs, and navigation/lifecycle/frame-tree events share that identity. Added redirect, late-response, main-frame, subframe, and fragment-navigation regression coverage, and extended the real Zen smoke test to check network IDs. Also fixed the Windows npm launcher noted by CodeRabbit. Please re-review the latest commit.

[SunkenInTime]

@greptileai Please review current head 83bf793, particularly the new Mozilla Add-ons authentication checker, tag-only publishing conditions, and AMO submission sequencing. The previous lifecycle/loader fixes remain unchanged. Local tests and actionlint pass; real AMO auth is pending repository secrets. No release was published.

[SunkenInTime]

@greptileai The release README now matches the new automation in d9bd7d6. Please review the latest head, including the AMO auth/submission changes from 83bf793.
