It takes 1.5 seconds to close a Tab in Safari. If you hold the close tab shortcut for long so that it closes all tabs the entire browser basically freezes.
I run into this daily. I don't understand how this got through QA
Oh, I had the same (?) issue! Restarting the app fixed it temporarily. Closing (copying to a text file) all tab groups fixed it completely. Until I accumulated them again.
