Earlier quoted context omitted.
Does it prioritize privacy? I haven't used Firefox in a long time, so my impressions of it are based on news stories, like them launching a partnership with sketchy VPN services or building in "easter egg" advertisements for television shows.
Firefox is still very imperfect in their prioritising of privacy, but when we're looking at the question of "use Chrome or Firefox", that's hardly significant in comparison. I'm curious what you're using currently if Firefox's privacy imperfections are of concern? Safari?
(Firefox has a good security team, but Chrome's is unmatched.)
