Unreleased

[0.1.5] - 2026-05-20

Fixed

• #15: python -m invisible_playwright fetch raised RuntimeError: no SHA256 for firefox-150.0.1-stealth-linux-x86_64.tar.gz in checksums.txt for every user because the parser kept the * binary-mode prefix that sha256sum writes in front of filenames. Now .lstrip("*") is applied to the key. Reporter + patch: @LostBoxArt. Unrelated to the firefox-N binary; existing caches still work, only first-time fetches were broken.

[0.1.4] - 2026-05-20

Fixed

• #13: every page that threw an uncaught JS error (e.g. bunny.net) crashed the Playwright client with TypeError: Cannot read properties of undefined (reading 'url'). Root cause: upstream Playwright Juggler added a required location field to the Page.uncaughtError event in the 2026-05-07 roll (microsoft/playwright@c8604ec); our fork was carrying the pre-roll schema in every firefox-N build. Fix matches upstream — Runtime.js builds the errorLocation, PageAgent.js forwards it on both worker and runtime error paths, Protocol.js declares the schema field. Reporter: @dionorgua.

Changed

• BINARY_VERSION bumped from firefox-3 to firefox-4. JS-only change inside chrome/juggler/; xul.dll and firefox.exe are byte-identical to firefox-3.

[0.1.3] - 2026-05-19

Changed

• BINARY_VERSION bumped from firefox-2 to firefox-3. The new archives on both Windows and Linux are built from a clean clone of feder-cr/invisible-firefox#stealth/150 — the consolidated source-of-truth fork (renamed from feder-cr/firefox; the companion feder-cr/firefox-stealth patches repo was deleted, all patches now live as commits on top of mozilla-firefox/firefox).
• The patched Firefox archive now ships the proper C++ implementation of windowUtils.jugglerSendMouseEvent, replacing the JS shim from 0.1.2.

C++ fixes landed in this release

• C1+C2: setDownloadInterceptor IDL + cpp (re-landed for FF150).
• C4: 5 nsIDocShell stealth attributes (fileInputInterceptionEnabled, overrideHasFocus, bypassCSPEnabled, forceActiveState, disallowBFCache).
• C5: LauncherProcessWin.cpp + nsWindowsWMain.cpp juggler-pipe handle inheritance — without this, the Playwright pipe disconnects immediately on launch.
• C6: juggler-navigation-started-renderer / -browser observer notifications in nsDocShell.cpp and CanonicalBrowsingContext.cpp — without these, Page.ready never fires and ctx.new_page() hangs.
• C7 (partial): storage stub for nsIDocShell.languageOverride. Workaround InvisiblePlaywright(locale="") recommended until full BC FIELD port lands.

Verified

• Both archives built from same source: feder-cr/invisible-firefox commit 68906f1f9c55.
• Windows + Linux smoke suite green: launch, ctx.new_page(), page.mouse.{move,down,up,click,wheel}, navigator.webdriver=false, sannysoft 32/33 PASS.
• SHA256 published in checksums.txt on the firefox-3 release.

Notes

• This is the first release with a native Linux build of the patched binary (previous firefox-3 draft mentioned shipping the Linux firefox-2 archive byte-for-byte; that no longer applies — Linux now has the full C++ patch series).

[0.1.2] - 2026-05-18

Changed

• BINARY_VERSION bumped from firefox-1 to firefox-2. The patched Firefox archive on GitHub Releases now contains the JS fix from 0.1.1 (every page.mouse.* / page.click() / locator.click() / mouse.wheel() failure on the FF150 binary). Users on 0.1.1 must run python -m invisible_playwright clear-cache && python -m invisible_playwright fetch to pick up the new archive.

Verified

• Archive integrity tests on both platforms: Windows zip extracted + booted via Playwright (mouse.move + click + page.click(selector) all succeed end-to-end), Linux tarball file-level checks (firefox/libxul.so sizes, byte-identity of patched JS files against Windows source). 21/21 assertions pass.
• SHA256 published in checksums.txt on the firefox-2 release.

0.1.1 - 2026-05-18

Fixed

• Critical: every page.mouse.*, page.click(selector), locator.click(), page.hover(), mouse.wheel() failed on the patched Firefox 150 binary with win.windowUtils.jugglerSendMouseEvent is not a function. The Juggler JS was porting calls to a Playwright-specific C++ method that was never landed in the FF146→FF150 port; replaced with the Mozilla chrome-scope win.synthesizeMouseEvent helper which is present in FF150. Six call sites patched across juggler/protocol/PageHandler.js and juggler/content/PageAgent.js. Reporter: @trob9 — #9.
• _linkedBrowser.scrollRectIntoViewIfNeeded() is now guarded at both call sites in PageHandler.js (dispatchMouseEvent and dispatchWheelEvent) — the method is not present on the shipped FF150 <browser> element, so the unguarded call threw before the mouse event was dispatched.

Added

• tests/test_mouse.py: 12-case regression suite covering every patched code path (mouse.move/click/dblclick/right-click, modifiers, locator.click/hover, wheel, manual mousedown+up, off-viewport move, humanize intermediate moves, scroll-and-click on offscreen element). Test cases inspired by microsoft/playwright-python/tests/async/test_click.py.
• Community standards: CODE_OF_CONDUCT.md, CONTRIBUTING.md, SECURITY.md, .github/ISSUE_TEMPLATE/*, .github/PULL_REQUEST_TEMPLATE.md.

Notes

• The Stealthfox humanize Bezier expansion continues to fire intermediate mousemove events; the swap to synthesizeMouseEvent does not change the human-trajectory behavior (verified by test).
• The reCAPTCHA v3 score (0.90) and FingerprintPro / CreepJS results documented in the README are unaffected — synthesizeMouseEvent is a legitimate Mozilla helper that does not increase the anti-detect surface.
• A binary refresh of the patched Firefox archive on GitHub Releases is required for users to receive this fix (the Juggler JS is shipped inside the archive). The BINARY_VERSION will be bumped to firefox-2 in that release.

0.1.0 - 2026-05-13

Added

• Initial public release.
• InvisiblePlaywright sync and async context managers — drop-in replacement for playwright.sync_api.Browser / async_api.Browser.
• StealthFox humanize hook: Bezier-curve mouse trajectories enabled by default.
• _fpforge Bayesian fingerprint sampler with ~400 fields per session.
• CLI: invisible-playwright fetch | path | version | clear-cache.
• Pinnable fingerprint fields via pin={...} (see docs/pinning.md).
• SOCKS5 / SOCKS4 / HTTP / HTTPS proxy support with auth.
• Linux x86_64 and Windows x86_64 binary support.
