I switched to Firefox both at home and professionally in 2020. Previously, my web browsers have been (in chronological order): Netscape 3.X, Netscape 4, Opera, Phoenix, Konqueror, Firebird, Firefox, Chrome, and now back to Firefox. I have exactly one very negative thing to say about Firefox. It absolutely sucks on machines with spinning rust and no SSD. It's the only piece of software I have that literally takes more than 2 minutes to start. With disk-IO pegged at 100% during the entire startup period. I'm assuming it reads through the myriads of files it has stored on disk, and that this is rather slow due to seek-times on HDDs. However, this is the major point I have against Firefox.
