I keep trying Firefox but Google services are absolutely terrible on it, and I spend a lot of time in Gmail/Drive/Docs/Hangouts so having two sets of browsers like another commenter here said is a non-starter for me (I've tried it).
A) (if possible) migrate away from the services you mentioned.
B) lock-in deeper and deeper with the biggest advertising company on the planet.
On the other hand, never say never to Google's dominance going out the window. They may find themselves in very deep trouble in the not too distant future.
