To chime in with some of the others, I decided to try out Firefox again [0] when the FF57 beta/nightly/whatever was first released and am very happy that I did!
Looks like that was ~48 days ago and I think I've opened up Chromium maybe two or three times since then.
(WRT extensions, LastPass was the only thing I "missed" (we have Enterprise for $work) although I normally use the CLI utility instead anyways. They came out with a beta a few weeks ago and it was actually working great until about two days ago when it suddenly broke for me. The other extensions I use -- uBlock Origin, Vimium -- have been working just fine.)
