Lots of non-Mozilla browsers based on the same browser engine for people tired of Mozilla doing stuff like this on Firefox, but who want to keep far away from browsers based on Google developed projects.

Realistically any functional and stable browser is going to have to be based on one of the big browser engines, if only because plenty of major websites just won’t work with anything but a big name browser engine. I’d rather be on something based on Gecko (Mozilla) than Blink( Google) or WebKit (Apple)
