rlbox VS fennecbuild

Firefox uses that to isolate third party libraries right now, like i.e. font rendering. It uses a framework called RLBox: https://github.com/PLSysSec/rlbox.

Seems like it could get a bit verbose when used all over the place but I’m not really used to the C++ world. Regardless I’m happy to see the effort being made beyond process isolation and OS capabilities.

I use a fork called Fennec which is Firefox stable with the proprietary bits removed. Also Mull is a great fork, which is Firefox Stable with most of the privacy enhanced features from arkenfox js which enables things like fingerprint resistance. This causes a lot more breakage though, so recommend to use it as a secondary browser. Both are available on fdroid, neither requiring Google Play.

Use this page to report Fennec F-Droid bugs. If you report an issue that also affects the official Firefox app, they'll notify Mozilla.

Bug report: FIDO2 WebAuthn not supported.

It isn't missing but removed due to depending on the proprietary Google Play Services library. There was a work in progress replacement: https://gitlab.com/relan/fennecbuild/-/issues/34

I would not use mull browser. I haven't gotten around in making a PSA. But the source code comes from 1 person in Russia. this is source code of mull, and the pg states its a fork of relan and if you click on relan's name you will see he is based in Russia. So one person is responsible for mull and another person is responsible for the back end. During this time of genocide of the Ukrainian people its my choice to not support anything with the word Russia. Each to their own.

It looks like this is the german language version of Firefox Focus. If you like firefox you should check out Mull. It is essentially a fennecbuild (DeBlobbed Firefox) that has been hardenned and contains upstream patches from the Tor Uplift Project.
