Unfortunately, it's not like it would realistically change the monopoly Google has over the internet. The greatest financial backer of Mozilla is Alphabet and if Firefox starts to gain too much traction, they will simply axe Mozilla and unless they manage to get another backer fast, Alphabet will have THE monopoly over the Internet.
Don't get me wrong, I'm doing my part and using Firefox (when it doesn't constantly crash), but Alphabet's holding way too many strings currently for any change to happen.
