BearBrowser v0.1.0-alpha

BearBrowser alpha — privacy / anti-fingerprinting browser.

Downloads

Platform	File	What's in it
Linux x86_64	bearbrowser-0.1.0-alpha-linux-x86_64.tar.gz	Full Gecko build WITH the engine anti-fp patches (canvas text-metric quantization + audio farble compiled into libxul). Extract, run bin/bearbrowser.
macOS	bearbrowser-0.1.0-alpha-macos-overlay.zip	Overlay build — LibreWolf engine + BearBrowser hardening prefs/policies (RFP, letterboxing, bundled Croscore fonts, Quad9 DNS, partitioning). Does not yet include the 3 engine patches. Unzip → right-click BearBrowser.app → Open.
Windows	—	Coming. Needs a Windows / cross-compile build.

Notes

• The Linux build is the reference for the anti-fingerprinting engine work. macOS will get a full engine build via cross-compilation; Windows is next.
• Alpha: Linux compiled clean on GCP; fingerprint scorecard + tor-mode (Windows-identity cohort) build in progress.
• macOS app is ad-hoc signed (not notarized) — right-click → Open on first launch.
