Iceraven
What Iceraven is
Iceraven is a free, open-source Android browser built from Mozilla’s Fenix Firefox, GeckoView, and Mozilla Android Components. It uses the Gecko engine and supports about:config, while aiming to provide more customization and more information about visited pages and browser interactions. Users can suspend tabs to help prevent memory-related removal and hide recently visited websites from the home page. The browser can attempt to install a larger add-on list through an AMO collection, although the project warns that most may not work. Releases are GitHub APK files for arm64-v8a, armeabi-v7a, x86, and x86_64 devices. Cross-device sync is listed. Installation requires allowing unknown-source apps and authorizing the APK-opening app. Iceraven is independent of Mozilla and volunteer-run, with no guarantees for security, updates, or stability.
Who it suits
Iceraven suits Android users seeking an open-source Gecko browser with about:config, tab suspension, and additional customization. It may also suit users comfortable installing GitHub APKs and accepting volunteer-run software with stated limitations.
