People ragging on the only viable browser solution we have… Firefox is rock solid, fast, tweakable, and keeps me as safe as any browser and my configs/habits can. I don’t care if management eats babies.
I use it on debian with celenity phoenix and a few about:config tweaks, also tweak’d the theme a bit. Extensions: ublock origin, sponsorblock, localcdn, consent-o-matic, containers, keepassxc-browser, and sometimes jshelter.
web browsing: solved
I have not left it yet but it has done some things that made me think significantly about replacing it. I think they do need their feet to the fire to stay somewhat good. That being said most every time there is drama around it I find the thing is really not it was blown up to be.
