Replace the same-origin checksum with a detached Ed25519 signature
(SHA256SUMS.sig) verified against a pinned public key before extraction,
closing #308: a compromised download mirror can no longer certify a
tampered binary. The signed manifest also binds the release version,
rejecting a forced downgrade to an older signed build.
Verification is mandatory and non-bypassable on the official download path;
custom CLOAKBROWSER_DOWNLOAD_URL mirrors keep the legacy skippable checksum.
Silent auto-update is preserved for everyone because only a constant public
key is pinned, not per-version hashes. Older installed wrappers are
unaffected — the version= line is ignored by their checksum parser.
Python uses cryptography; JS uses node:crypto. Adds tamper, downgrade, and
fail-closed tests in both languages.
Headed launches applied a fixed emulated viewport on top of the real
browser window, yielding outerWidth < innerWidth (an impossible window).
Default headed new_page()/new_context() to no_viewport so the page tracks
the real window; headless keeps a deterministic viewport. Covers Python
launch/launch_context/launch_persistent_context (+async) and the JS
Playwright/Puppeteer wrappers. Explicit viewport still honored.
Zero typing_delay so the '!'-uses-CDP assertion no longer races the
5s default timeout under random thinking-pauses + CI load. Test only
checks which chars route through CDP, not timing.
Sideloaded Widevine works on the first launch of a persistent context
instead of needing a manual two-launch hint-file workaround. The wrapper
writes Chromium's CDM hint file into the profile before launch when a
WidevineCdm directory is present next to the binary.
- New cloakbrowser/widevine.py and js/src/widevine.ts: resolve a sideloaded
CDM (CLOAKBROWSER_WIDEVINE_CDM env var, else next to the binary) and seed
the hint file. Linux only; no-op elsewhere. CLOAKBROWSER_WIDEVINE=0 disables.
- Never bundles/downloads/copies the CDM (proprietary); seeds only when the
user-provided CDM is already present.
- Wired into launch_persistent_context[_async] and launchPersistentContext.
- README + js/README: Widevine / DRM section, env vars, FPJS tradeoff note.
- Tests: tests/test_widevine.py, js/tests/widevine.test.ts, persistent-context
integration assertions.
Mirror the JS fix from #303 in the sync and async Python actionability
checks: compute and apply the iframe coordinate offset before
elementFromPoint, and fail open when the check itself cannot run. Add
fail-open regression tests for both Python and JS.
Frame-level methods (click, dblclick, hover, dragAndDrop) passed the raw
timeout to each sequential operation independently, causing 3x actual
wait time when elements don't exist. ElementHandle methods had a similar
2x issue between actionability and pointer-events checks.
Port the deadline + remainingMs() pattern already used by page-level
methods. Also fix bot detection test selector after site added a hidden
duplicate submit button.
Bypass Playwright's CDP Fetch.authRequired interceptor for authenticated
HTTP proxies by passing inline credentials via Chrome's --proxy-server
flag. Chrome sends Proxy-Authorization preemptively, avoiding the 407
round-trip that breaks on some proxies and Google domains (#182).
Gated on platform (linux-x64, windows-x64) and binary version >= 146.0.7680.177.5.
Unsupported platforms fall back to Playwright's proxy dict.
Puppeteer falls back to page.authenticate() on unsupported platforms.
Expose userDataDir support via launchPersistentContext() for
cloakbrowser/puppeteer, matching the existing Playwright API.
Includes proxy auth, geoip, and humanize support.
Add `extension_paths` parameter to all launch functions (Python + JS) for loading Chrome extensions.
Resolves paths to absolute, injects `--load-extension` and `--disable-extensions-except` flags via `build_args()`.
Note: Extensions require a persistent context (`launch_persistent_context`) to function — this is a Chromium limitation.

* fix(proxy): log when SOCKS5 credential auto-encoding rewrites URL (#157)
Auto URL-encoding of SOCKS5 credentials (added in v0.3.26 to fix Chromium's
'=' truncation bug) currently happens silently. Users debugging connectivity
have no way to know the wrapper rewrote their proxy URL — the original #157
thread took 8 round-trips to surface this exact ambiguity.
Emit a log when re-encoding actually changes the URL: INFO on Python's
'cloakbrowser' logger, console.debug in JavaScript. Stays silent on
already-encoded inputs and credential-less URLs to avoid false-positive
noise. Credentials are not included in the log message.
Tests: 3 new cases per language (Python caplog, JS vi.spyOn console.debug)
covering trigger / silent-when-encoded / silent-when-no-creds.
* fix(proxy): gate log on credential change, not full URL diff
Per Copilot review on #209: urlparse cosmetically lowercases scheme and
hostname, so comparing the full reconstructed URL to the input would emit
"Auto URL-encoded SOCKS5..." even for inputs like
`socks5://USER:pass@HOST.com:1080` where no credential encoding happened.
Compare raw vs encoded user/password substrings instead. Mirror the same
condition in JS for parity (JS's manual parser preserves case today, but the
credential-level compare is more robust against future changes).
Adds one regression test per language.
The humanize layer hardcoded timeout=2000ms for element lookups, causing
locator.click() and page.click() to fail instantly instead of retrying
for 30s like standard Playwright. Aligned all defaults to 30000ms across
Python sync/async, JS Playwright, and JS Puppeteer paths. Bumped the
outer retry sleep from 200ms to 500ms for DOM mutation settle time.
Chromium's --proxy-server parser truncates passwords at '=' and other
special chars, causing SOCKS5 auth to silently fail and fall back to
direct connection. The dict path already encoded creds; now the string
path does too. Idempotent: pre-encoded input stays encoded.
Python: add async counterpart to launch_context(). Forwards all kwargs to
browser.new_context() — enables storage_state, permissions, extra_http_headers,
etc. without needing a persistent profile folder.
JS: launchContext() and launchPersistentContext() silently dropped unknown
options. New contextOptions field in LaunchContextOptions is spread into
newContext() to forward arbitrary Playwright context options (e.g.
storageState, permissions, geolocation).
Route SOCKS5/SOCKS5h proxies via --proxy-server Chrome arg instead of
Playwright's proxy dict (which rejects SOCKS5 with credentials).
Handles string URLs, Playwright dicts, IPv6, bypass lists.
SOCKS5 geoip exit IP resolution uses socks-proxy-agent (optional peer
dep). Falls back to DNS if not installed.
Remove --disable-blink-features=AutomationControlled (dead, binary handles
navigator.webdriver at source level) and hardcoded GPU vendor/renderer flags.
Binary auto-generates diverse GPU profiles from fingerprint seed. Improves
fingerprint diversity -- previously every user shared the same GPU string.
Bump to v0.3.21.
Two ways to spoof WebRTC ICE candidate IPs:
1. --fingerprint-webrtc-ip=auto in args: resolves proxy exit IP via
HTTP call through the proxy (ipify.org). No extra deps needed.
2. geoip=True: auto-injects the flag for free (exit IP already
resolved during timezone/locale lookup, zero extra network cost).
Explicit IP (--fingerprint-webrtc-ip=1.2.3.4) also supported.
User-provided values always take precedence.
Python + JS wrappers, README docs, tests.
Verify that HTTP errors (429, 503, etc.) from cloakbrowser.dev
correctly trigger GitHub Releases fallback for both binary and
checksum downloads. Also test that custom CLOAKBROWSER_DOWNLOAD_URL
disables fallback, and both-sources-fail returns gracefully.
- Remove locale and timezone_id from Playwright context kwargs (CDP)
- Pass timezone via --fingerprint-timezone binary flag (process-wide)
- Pass locale via --lang + --fingerprint-locale binary flags
- Accept both timezone and timezone_id param names silently (no deprecation)
- Update all wrapper tests to verify binary args, not CDP context params
Bump version to 0.3.9. Extract shared buildArgs into js/src/args.ts (DRY),
guard console.debug behind DEBUG=cloakbrowser env var, strengthen caplog assertion.
- Rename timezone_id → timezone in launch_context(), launch_persistent_context(),
and launch_persistent_context_async() (Python)
- Extract _migrate_timezone_id() helper for deprecation compat (DRY)
- Always pop timezone_id from kwargs to prevent override via context_kwargs.update()
- Use FutureWarning (visible by default) instead of DeprecationWarning
- JS: deprecate timezoneId on LaunchContextOptions with runtime shim
- Extract migrateTimezoneId<T>() shared helper in playwright.ts (DRY)
- Bump version to 0.3.7 in _version.py and package.json
- Add 4 Python + 4 JS unit tests for deprecation compat behavior
The `proxy` parameter now accepts a Playwright proxy dict
({server, bypass, username, password}) in addition to URL strings.
Dict proxies are passed directly to Playwright, enabling bypass
lists and other advanced proxy options.
- Add ProxySettings TypedDict for Python type safety
- Extract server URL from dict proxies for geoip resolution
- Handle dict proxy args/auth in Puppeteer wrapper
- Strip inline credentials from dict proxy server URL in Puppeteer
- Fix JS launchContext() double-setting timezone (binary flag + context)
- Remove unnecessary non-null assertions in TS geoip helpers
- Use nullish coalescing for password fallbacks
- Add unit tests for geoip with dict proxy input
Check for newer wrapper versions on startup (once per process).
Python queries PyPI, JS queries npm registry. Respects
CLOAKBROWSER_AUTO_UPDATE=false and CLOAKBROWSER_DOWNLOAD_URL
(custom mirror mode skips external registry calls).
Includes unit tests for both languages covering: update detection,
env var gating, network error handling, and once-per-process guard.
- Add PLATFORM_CHROMIUM_VERSIONS map (Linux=v145, macOS=v142)
- Add get_chromium_version()/getChromiumVersion() for platform-specific version
- Make auto-update check release assets before offering updates
- Scope version markers per-platform (latest_version_linux-x64)
- Support 5th version segment for hotfix builds (e.g. 145.0.7632.109.2)
- Derive AVAILABLE_PLATFORMS from version map
launch() and launch_context() now inject --timezone and --lang binary
flags when timezone/locale params are set. Previously only the Playwright
context layer was configured, leaving a detectable mismatch that CreepJS
flagged as a bot signal.
