A custom Fenix (Firefox for Android) build that ships with:
- the Symfony Bookmarks extension pre-installed,
- uBlock Origin pre-installed,
- the Symfony Bookmarks dashboard as the home / new-tab page.
This repo contains only the customization (firelex-patch/). It is not a fork of
Firefox: the CI checks out upstream mozilla-firefox/firefox@release fresh at build time
and overlays these patches on top — no multi-GB Firefox source is mirrored here.
GitHub Actions → build-fenix → Run workflow (branch main). The APK lands in the
fenix-debug-apk artifact (arm64-v8a).
Each successful run attaches the APK as the fenix-debug-apk artifact on the
Actions run page — download it there and
sideload / adb install it. To publish a shareable APK, attach it to a
GitHub Release; binaries are intentionally kept out of git.
firelex-patch/apply.sh runs in CI after the upstream checkout:
- copies
overlay/files into the tree (built-in extensions installer, launcher icon), - unzips the bundled extensions into
assets/extensions/, - applies
patches/*.patch(install the extensions, route the home to the dashboard, rename the app).
If a patch stops applying after an upstream release bump, the step fails loudly — rebase
that one patch. See DESIGN.md (architecture) and firelex-patch/README.md (details).
