I use Waterfox every day. Mozilla may want Firefox to be a Chrome clone, but I still use my 'old fashioned' extensions and don't need new (pardon the pun) chrome all over the place.
I've been using it too, especially since FF 57 for some reason breaks images on some websites. I've also been using Qutebrowser some, which I love for the keybindings.
I find it hilarious that while they took the time to give FF57 a new "touch" UI, the zoom gesture is still only enlarge the font size.
go to about:config and set browser.zoom.full to true
this will cause the whole page to get zoomed.
