For Android users seeking a privacy-focused browser, Privacy Guides recommends Mull:
Mull is a privacy oriented and deblobbed Android browser based on Firefox. Compared to Firefox, it offers much greater fingerprinting protection out of the box, and disables JavaScript Just-in-Time (JIT) compilation for enhanced security. It also removes all proprietary elements from Firefox, such as replacing Google Play Services references.
Mull enables many features upstreamed by the Tor uplift project using preferences from Arkenfox. Proprietary blobs are removed from Mozilla’s code using the scripts developed for Fennec F-Droid.
I can’t think of a situation in which they’d ever want to use the front camera, since it’s an AR project, but I might just have to make it an option to fix weird issues like this.
They might also have a USB camera.
