Download for Linux & macOS

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's been mounted and run on real Mac hardware to confirm it actually launches and defaults to LuisSearch. 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.
