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
Using Firefox since v1.0.2 and no plan to switch to any other browser.
All concerns that people have about Mozilla/Firefox, can be solved by tweaking preferences in about:config; nothing is hard-locked by Firefox developers.
