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.

You need to make sure Files is being indexed, I think the Documents directory indexing, for the clipboard history to work.
