Firefox does have adblock, but: - only certain % of people use FF - of those, only certain % of people install Adblock - of those, only certain % block also text ads But, if IE (most used browser) would contain "block all ads" dedicated button, that would really bring Google much trouble. So those two things are not comparable. But I still think that M$ will not do that...it's too dangerous for everyone and I don't agree that the fear of this was the primary Google motivator to create this. In this case, I do believe what they proclaim - they want to speed up the browsers development in general, since it's in their interest.
