Tahoe has this really cool clipboard history feature that just does not work on my work laptop. Maybe some corporate keep-me-safe-ware is preventing it from working but my third-party app, Maccy, has no problem at all, so I guess it's just Apple being Apple these days.
I also held out for as long as possible using Safari, but I had to switch to Firefox. Every once in a while I forget the reason I switched and try to switch back and then get reminded. I'm currently in a "I can't remember the reason, but I'm too lazy to go find out" phase. I'm also one of those weirdos that liked the Safari compact tabs and I'm sad they removed it.
