I’ve used edge before my university disabled profile syncing (only reason I was using it, to be honest). Edge was fine. Switched to Firefox just to see how it is nowadays, never looked back. Honestly, can’t think of any extension I’m missing. Got quite a few myself, but probably not the same niche as you.
So far I haven’t encountered broken websites yet. Fingers crossed to keep it that way. Though I’ll probably steer clear of such a website unless absolutely necessary.
