Two service-worker leaks. Running jobs were only bounded by their watchdog, so
a command flood could hold many timers and results for up to JOB_TIMEOUT_MS;
cap concurrent jobs at 32 and reject beyond that, since a clear error beats an
unresponsive worker. Window aliases were never removed, so storage kept an
entry for every window the user had ever renamed.
Prune aliases against the live window set on list, rename, and close rather
than only on close, because windows also disappear without going through
windows.close.
Also extract the repeated job summary in perf.status into a helper.

- 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.

- Change nav open and open-wait to avoid activating newly created tabs unless
--focus is explicitly requested.
- Send background=true for default opens so older or remote extensions also
avoid stealing focus even if they ignore the new focus flag.

- Bump package and extension metadata to 0.12.3.
- Add regression coverage for CLI help, wire payloads, and extension behavior.
- Respect the globally selected browser when renaming client aliases.
- Pass the resolved local profile into sync and async local transports so
BROWSER_CLI_PROFILE is honored consistently.
- Stop tabs.active from explicitly focusing the OS browser window, avoiding
virtual-desktop jumps during tab activation.

- Add explicit client handling for passive remote discovery without noisy PQ warnings.
- Keep behavior covered with updated unit, integration, and extension tests.
Closing many tabs previously meant one IPC round-trip per tab
(tab.close() in a loop). Add a single batched path so callers can
close N tabs in one command, reusing the existing large-operation
throttle so the browser UI stays responsive.
- extension: tabs.close accepts tabIds: number[]; new branch feeds
the array through processInBatches/chrome.tabs.remove
- sdk: tabs_close(tab_ids=...) takes tab IDs or Tab objects; the
payload always carries "tabIds" (null when unused)
- tests: cover id-list and Tab-object batch close in test_api.py
- bump 0.10.3 -> 0.10.4 (pyproject.toml, manifest.json)
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.
- Add shared browser error URL detection for Chrome, Edge, Brave, and Firefox-style about:error pages.
- Short-circuit read-only DOM and HTML commands with safe fallbacks when tabs are already on browser error pages.
- Fail navigation waits, DOM waits, polling, and URL watches with clearer error-page messages.
- Bump package and extension version to 0.9.8 and extend regression coverage for cross-browser error-page handling.
- Treat chrome error page script failures as transient during injection retries.
- Return safe fallback values for read-only DOM commands when tabs land on browser error pages.
- Improve URL watch handling by checking pending URLs and reporting last seen URL/status on timeout.
- Bump package and extension version to 0.9.6 and add regression coverage for error-page behavior.
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)
