But Google's revenue isn't only generated by Chrome.
And even if it was, Mozilla shouldn't try to chase that revenue. It should generate only enough revenue to sustain and futher develop web technologies which allow people to stay free on the web.
The majority of Google's revenue is generated through websites accessed via browsers. I don't know how much Google spends on controlling the browser market with Chrome, but I have little doubt that Google would spend a billion per year on it if they had to.

It has been driven by chrome though (by having improved web standards in general - note the past-tense). However the future is looking far more murky, now on top they are making changes that benefit only google (crippling ad blockers for one).
