Sorry but they the ones that took away the hundreds of extensions before. With great power comes great responsibility, not great laziness.

Well, most extensions seem to work great already. But that requires using either Nightly Firefox (and some hacks) or using a fork (like Iceraven) that loads a different extension list.

So, it's easier to switch to browsers like Kiwi Browser (privacy concerns aside so be cautious!) if you want a better extension support experience. Bromite and Vivaldi also have great built-in adblockers but sadly no full extension support.

So, I dropped Firefox on all my devices and moved to Vivaldi + Kiwi Browser and that works like a charm.
