> Firefox haven't caved in so far. Why do u think it might in future?
Because pretty much all their revenue comes from Google.
Making Firefox even less desirable by "googlifying" it pushes Firefox users away and kills its image of a viable competitor. That's exactly what Google is paying for.
Why would Google destroy the cover they have for keeping control over Chrome and 70% of internet users, just to squeeze a bit more ad revenue from what, 2% of users?
I think Google will try to annoy Firefox users into using Chrome instead via things like needless captchas.
