yo question ab firefox coming from dude who knows very little ab it, i watched a video browser tier list by eric murphy and he listed hardened firefox in S tier, do u reach hardened firefox by downloading configs for it off github? how reliable is it and do things tend to crash if u try to have many options at the same time (like an amalgamtion of stuff from different ppl in order to reached a specific desired outcome, in terms of options, security settings and look)?
