I had to ditch chrome because it performed abysmally, tried to use Safari but just couldn't get used to it, so went back to Firefox and was very pleasantly surprised ... great Mac OS experience.

That has to be a joke, zooming barely works on macOS (and has to be enabled using an about:config flag). It's decent if you just use an old fashioned mouse though and not a magic trackpad.

Perhaps your experience not only isn't universal, but the magic trackpad may not be all that magical after all.

True - zooming is an abomination compared to Safari ... but I don't zoom that often, so of course, YMMV.

They have in theory, but the fix isn't working for a lot of people, and Firefox continues murdering their battery. Firefox devs are aware but AFAIK their attention is focused elsewhere at the moment. Quite sad, because of all the people I got to switch to Firefox, all but one that experiences this issue has switched back to Chromium. Privacy and fighting browser hegemony is great, but stark few people are willing to sacrifice nearly half their battery life for it.
