I’m back to Firefox after many years, it’s quite good and I don’t miss anything from Chrome other than one click translate page button. Also looks like FF has caught up Chrome performance-wise. It’s fast, it respects your privacy, very nice!
I've been using Firefox as my daily driver for perhaps a year or more now.
As well as the translate page button, the other great feature chrome has that I miss dearly is the highlights chrome has in the scrollbar when doing a ctrl-f find-in-page. That is super-useful and a real pain in the arse that Firefox does not support it.
I played around with prototyping an extension to replicate it (or as close as I could get) but it was hard to nicely override the ctrl-f hooks.
It actually feels faster than Chrome to me. I've been primarily on Firefox for the past few months and was really surprised to find Chrome not feeling as responsive when I tried to use it recently.
