Activate it and check the Selinux context it runs as. Last I checked it has still been running as “untrusted_app”, while for a sandboxed multi-process structure, there should be “isolatedProcess” at least for every renderer process.
No direct, but a indirect, recomendation.
If your about security (especially on GrapheneOS) don’t bother with Firefox on Android. https://madaidans-insecurities.github.io/firefox-chromium.html#sandboxing
This is just one example since I’m sure you read the GrapheneOS documentation on browsers?!
If its just for depening knowlege enjoy the trip and research.
I’ve did the same, even used Mull as a secondary browser. But all research leads (back) to chromium is more secure, regardless of how much Firefox has improved.
In times of Mull to have a decent alternative for people refusing to use a chromium based browser.
Pretty much obsolete now as long there is no replacment for it now
Privacy Guides didn’t recommend Firefox, they recommended Mull.
The reason for recommending it is simple: If one is ignorant enough to use Gecko-based browsers on Android, then we can’t really do anything about it, so at least use Mull for some badness reduction.
