IronFox is a fork of Divested Computing Group’s Mull Browser, based on Mozilla Firefox. Our goal is to continue the legacy of Mull by providing a free and open source, privacy and security-oriented web browser for daily use.
Version IronFox v140.0.4 released, .apk available for download here.
More discussion about the browser here.
Unfortunately, not available in FDroid yet.
It’s not on F-Droid, but it is on Accrescent
I’ve been using it as my phone browser and have zero complaints.
You can add the IronFox repo to Fdroid; found here.
Just started using it. Love it, although it does hang when loading pages. Think that’s due to the security/privacy features?
Don’t know, might want to check out their git page and look for the issue, or report it.
