Agree on the goal, IMO it would be very very nice to work on top of a browser that is NOT chromium based...just to challenge the dominance of google. Thus, I would suggest Firefox
And you would be wrong. Firefox security is absolutely trash
and ironically all the supposed privacy forks don't even bother to allow you to fully disable DRM either
Can you point to some resources to understand better the matter? Why is it trash?
Look up sandboxing of a tabs browsing context
Firefox lacks this
Firefox containers aren't useful in that regards?
I don’t think so. Firefox is kinda EOL at this point. In maintenance mode
