Just providing my piece of anecdata that me, and everyone in my family, have switched to Firefox Quantum on all our desktop machines, and aren't looking back.
(My wife has never used anything but FF, but she begrudgingly updated, and is now a happy user. I switched from Chrome; I can get way more tabs open on my cheap Asus 2-in-1 with FF.)
