- Add a neutral WebExtension API adapter that uses Firefox browser.* or Chromium chrome.* without mutating globals.
- Switch extension runtime code to the adapter and add Firefox-specific typings for tabs, windows, tab groups, storage, scripting, and native messaging ports.
- Fix Firefox temporary add-on instructions to load the packaged manifest with background.scripts instead of the Chromium service worker manifest.
- Detect Firefox in clients.list via runtime.getBrowserInfo and keep Chromium user-agent fallback support.
- Make navigate.open wait briefly for Firefox to replace initial about:blank with the requested URL.
- Add JS coverage for API selection, clients.list browser detection, and Firefox navigate.open URL polling.
- Bump package and extension version to 0.15.2.
- Add Firefox as an install target with native messaging manifest support.
- Generate Firefox-specific extension packages with Gecko metadata and AMO-compatible manifest transforms.
- Keep tab group commands available in Firefox through dynamic tab group API helpers.
- Avoid Firefox linter warnings for static tab group API references and direct eval tokens.
- Add Firefox packaging and installer regression coverage.
- Bump the package and extension version to 0.15.1.
- Add safe-by-default policy gates for raw command surfaces: command, script, and serve-http /command.
- Require explicit opt-ins for page reads, browser control, and high-risk commands such as dom.eval, storage.*, and screenshots.
- Remove all cookies support from CLI, SDK, extension commands, permissions, constants, docs, and tests.
- Add diagnostic, events, watch, workspace, remote, raw command, script, HTTP gateway, tree-view, session import/export, and extension info/capability commands.
- Add Chrome Web Store packaging that strips manifest.key while keeping local packages with a stable native-messaging extension ID.
- Bump browser-cli and extension version to 0.14.1 and cover the new behavior with pytest and extension packaging tests.
BREAKING CHANGE: cookies commands and the b.cookies SDK namespace have been removed; generic raw command execution now blocks non-safe commands unless explicitly allowed.
Restructure the MV3 background worker from a monolithic core.ts/index.ts
into a class-based command architecture. Behavior is identical — the 83
registered commands dispatch byte-for-byte the same as before.
Structure
- One class per command group, each extending CommandGroup and exporting a
`commands` map keyed by the full command id ("tabs.close"). Groups:
Navigation, TabsMutation, TabsQuery, Groups, Windows, Dom (dom/extract/
page), BrowserData (storage/cookies), Session (session/clients + autosave
+ lazy-tab activation), Perf (perf + jobs.status/cancel), Extension.
- CommandRegistry merges the group maps (throws on duplicate ids), routes
background specs to JobManager and paginates array results via
makePagedData. JobManager owns the job map + lifecycle. NativeConnection
owns the native-port lifecycle and the inbound message router.
- index.ts is now thin wiring: JobManager -> ctx -> assembleRegistry ->
onActivated -> NativeConnection.start().
- Infra classes live in classes/ (PascalCase, file = class name); command
groups in commands/; shared helpers split out of core.ts into core/
(errors, throttle, scripting, tab-helpers, group-helpers, storage); all
types moved into types/ (json, jobs, session, tabs, messages,
command-args) behind a barrel.
DRY cleanup
- resolveTabUrl(tabId) and assertScriptableUrl(url, action) collapse the
tab/URL-guard boilerplate duplicated across dom.ts and browser-data.ts.
- processInBatches() centralizes the throttled, cancellable batch loop
shared by tabs.close, group.close and tabs.merge_windows.
- captureCurrentSession() dedups the snapshot-and-signature block shared by
session.save and the autosave path.
- DomArgs type alias replaces 21 inline ContentArgs & { tabId? } copies.
- Drop fetchTabHtml's redundant retry loop (executeScript already retries
transient frame/tab errors), a dead tabInfo import, and two stale
comments referencing a removed asArgs helper.
Type safety & tests
- Full noImplicitAny; no `any`/`unknown` annotations remain in src.
- JS unit-test harness using node --test + node:assert (zero new deps),
bundled via the existing esbuild. Covers JobManager retention/lifecycle
and the autosave listener-wiring/debounce with an in-memory chrome mock.
- The structural pytest checks track the new file homes and the centralized
processInBatches helper.
Verification: npm run check:extension green (tsc + esbuild 84.5kb +
node --check + 18 JS tests); uv run pytest -q -> 409 passed, 105 skipped.
No version bump.
- Add throttled large-operation handling for tab, group, and session commands.
- Introduce performance profiles, audible-tab aware gentle mode, and job progress tracking.
- Support background session restores with status/cancel commands and lazy placeholders.
- Expose new perf and extension CLI groups plus matching Python SDK methods.
- Preserve pinned tabs during session snapshots and debounce auto-save updates.
- Bump browser-cli and extension versions to 0.10.0 and add pytest-cov to dev deps.
- Add coverage for performance controls, background jobs, lazy restores, and tab metadata.
Security:
- serve.py: server now sends nonce challenge before accepting any command;
clients sign nonce + SHA256(canonical_payload) with Ed25519 key
- New --authorized-keys FILE option for serve; token auth still works as fallback
- Connection limit: BoundedSemaphore(64) in serve.py
- Secure file creation with os.open(..., 0o600) for token/key files
- New auth.py module: keygen, file key load/save, SSH agent protocol (pure Python),
sign/verify helpers compatible with both file keys and agent-held keys (YubiKey,
TPM, gpg-agent)
Features:
- YubiKey support via SSH agent protocol — no new runtime deps, just $SSH_AUTH_SOCK
- New `browser-cli auth` command group: keygen, trust, show, keys
- Global --key PATH flag (or BROWSER_CLI_KEY env) selects signing key;
pass "agent" or "agent:<selector>" to use SSH agent key
- BrowserCLI Python API gains key= parameter
Bug fixes (11 issues across two review passes):
- client.py: check response is not None before json.loads
- native_host.py: _read_exact_stream loop handles EINTR short reads; fix Windows
Listener leak on accept error
- __init__.py: open_wait / tabs_watch_url raise RuntimeError instead of silent None
- extension/tabs.ts: dedupe skips tabs without URL; tabsSort uses pendingUrl fallback
- extension/session.ts: removeListener before addListener prevents duplicate handlers
Breaking: TCP serve protocol now sends a challenge frame first (v0.9.0)
