A while ago, I used to recommend Waterfox. Its mostly a dead project now & differing by a wide margin with Firefox upstream. Updates are few and rare.

I use Vivaldi at present. It is mostly fine. Plugins work fine & the web/mobile sync is decent. No crashes or memory overflow on either platform - using since 6 months approximately.

My SO uses Edge and she has been reasonably happy with it

Have you tried LibreWolf? I'm not a big fan of a bundled ad blocker, but they seem less ambitious and therefore more sustainable. (Only tweaking defaults of FF itself.)
