firefox_antidetect_patch (150.0.1) rev 15

This release makes the bundled font set look identical on Windows, Linux and macOS.

Until now each operating system listed the bundled fonts through its own backend (DirectWrite, fontconfig, CoreText), and they did it a little differently. macOS in particular exposed fewer families than the other two. From this build the family list is built from one checked-in manifest and filled the same way on every platform, so the exposed set is the same everywhere. The real font files are still used to render the glyphs; the OS only draws them.

Highlights:

• Same font family set on Windows, Linux and macOS, by construction (72 families).
• macOS now exposes the complete set (it was missing several families before).
• Font faces are loaded straight from the bundled files, including the multi-face .ttc collections, picked by PostScript name so the right face is always used.
• Removed a good deal of now-unused font code.
• Fixed packaging of the font manifest inside the macOS app bundle.

Every platform build is checked in CI to expose exactly the same set of families with no host fonts leaking through, and the binaries are driven end to end against the open detector test suites (CreepJS, BotD, FingerprintJS, sannysoft) before shipping.

Downloads: Windows x64, Linux x64 and arm64, macOS x64 and arm64.

firefox_antidetect_patch (150.0.1) rev 14

This is firefox-13's binaries, unchanged, republished here on the source repository so every tool that fetches the patched Firefox pulls it from one place. Nothing about the browser changed since firefox-13 — same five archives, same checksums.

Built from firefox_antidetect_patch @d55f829ab4ca.

Usage counter

Anonymous launch counter. Every time the patched Firefox starts, it issues a single HTTPS GET to the launch.txt asset attached to this release. The number of total launches across all users equals the download_count of launch.txt (visible via the README badge or gh api repos/feder-cr/invisible_firefox/releases/tags/usage-counter).

The ping is gated by the pref invisible_firefox.usage_ping.enabled (default true). To disable permanently, remove the corresponding hook in browser/components/BrowserGlue.sys.mjs and rebuild from source.

This release is intentionally not a Firefox build — it only exists to host the counter asset.
