Favorite search engines or browsers?

Been paying for Kagi for a few months and really like it.

Desktop browser, I bounce around and am never happy. I want to get back on Firefox, and thought I would when the latest version came out and finally added native vertical tab support, but turns out it still doesn't have tab grouping/workspaces (saw that it's in development but haven't seen a timeline) so I've gone back to Vivaldi for now.
