Well, I don’t mean downgrade him totally! Give him super strength or something but take it to its conclusion.
Authors realized this problem with Flash, so they added a mildly magic mystery Speed Force thing that solves the too-many-Gs problem with “nah he just slows time down or something and the Speed Force is mysterious and different” iirc.
But without the handwaviness he’d need to watch acceleration and calorie counts and speed up his thoughts and not slip and fall into an inertial death. If that makes sense (-‿-")
I use Firefox everywhere else, but for my Android I’m on Brave.
Sure, adblock and tab grouping is a plus but my main reason I use it (i.e. over Firefox) is because of memory. When I have six FF tabs open, my Samsung model shoots at least three down the moment I enter another activity or open a new tab. They survive on Brave.
I’d still use Brave on iOS devices too – as another commenter said, it’s a webkit reskin but at least it’s got good Adblock.
