It exposes about:config, supports a wider range of add-ons than stock Firefox for Android, and tries to replicate the desktop Firefox experience on mobile. Updates come through GitHub releases. It’s aimed at people who want to tweak their browser. IronFox comes from Mull, which itself is a privacy-hardened Firefox fork. It removes more telemetry than Iceraven, disables features that leak data by default (WebGL, for example), and keeps the interface stripped down. It’s on F-Droid and Accrescent as well as GitHub. The trade-off is that some websites break because of the aggressive defaults. ...

Firefox 4 just dropped and you want to try it without losing your current setup? You can run both versions at the same time.

Firefox 4 runs as firefox-4.0. Both show up in your applications menu, or you can launch them from the terminal whichever you need.
