Full changelog

firefox-3 — clean fork build from feder-cr/invisible-firefox#stealth/150.

Built from a fresh clone of the renamed fork (no hand-patches in dist/, no
hidden modifications). Includes all C5-C7 fixes that landed 2026-05-19:

C5: LauncherProcessWin + nsWindowsWMain juggler-pipe handle inheritance — without this, the pipe disconnects immediately on launch.
C6: juggler-navigation observer notifications in nsDocShell + CanonicalBrowsingContext — without these, Page.ready never fires and ctx.new_page() hangs.
C7: storage stub for nsIDocShell.languageOverride — partial; InvisiblePlaywright(locale="") workaround still needed for now.
Proper C++ jugglerSendMouseEvent (issue #9 fix, replaces the JS workaround that was in firefox-2).

Verified locally

Launches under Playwright (smoke test PASS)
ctx.new_page() returns 1-2s (smoke test PASS)
page.mouse.{move,down,up,click,wheel} all 5 ops PASS
navigator.webdriver = false, UA / languages / platform overrides applied
bot.sannysoft.com 32/33 PASS (the 1 fail is "Chrome (New)" — correctly identifies as Firefox)

Supersedes

This release supersedes firefox-2 which had a JS-only workaround for issue #9. After this, invisible_playwright BINARY_VERSION will be bumped to firefox-3 in 0.1.3.

Both Linux + Windows from same source

Both binaries built from feder-cr/invisible-firefox#stealth/150 HEAD (commit 68906f1f9c55) with the same patch series applied. Previous firefox-2 Linux was a copy of firefox-2 Linux because no Linux build host was available; this release closes that gap.

Breaking Changes

Supersedes `firefox-2`; the JS-only workaround for issue #9 is removed and replaced with a proper C++ implementation.
