Download for Linux

A real Firefox/Gecko build, repackaged with LuisSearch preconfigured as the default search engine via Firefox's own enterprise policy system -- same rendering engine, different default.

Linux x86_64
.tar.zst · ~113MB · portable, no install needed
Download luisbrowser-linux-x64.tar.zst
  1. Extract it: tar --zstd -xf luisbrowser-linux-x64.tar.zst
  2. cd luisbrowser
  3. Run it: ./luisbrowser
macOS (Apple Silicon & Intel)
.dmg · ~207MB · real LuisBrowser.app, ad-hoc signed
Download LuisBrowser-macOS.dmg
  1. Open the .dmg and drag LuisBrowser to Applications
  2. Right-click → Open the first time (it's ad-hoc signed, not notarized, so Gatekeeper will ask once)
Both of these are real, not mockups. Under the hood it's official Firefox with a distribution/policies.json that sets LuisSearch as the enforced default search engine, disables telemetry/Pocket, and points the homepage at LuisBrowser welcome page. No recompilation of Gecko.

The macOS build is a genuine LuisBrowser.app, built by an actual GitHub Actions macOS runner (not faked from Linux) -- Apple's disk-image compression inside the official Firefox .dmg can't be unpacked or repacked from Linux (verified: standard extraction tools can read the partition table but not decompress the filesystem inside), so this was built on real macOS, then ad-hoc code-signed so it will actually launch. It isn't notarized by Apple, so Gatekeeper will show an "unidentified developer" warning the first time -- that's expected for an independent build, not a bug. Windows isn't packaged yet.
