Are Google shooting themselves in the foot

Google are backing Firefox, so much so that they are even giving away $1 per referral to each adsense publisher. My thoughts are that most of the people I know...download extensions to Firefox such as Adblock as soon as they install Firefox. This is one of the selling points of Firefox that no longer do we have to see big flashy annoying ads, which gives us as the user the control to see what we want.

In the long run if more and more users take up Adblock they would be denying Google a large chunk of their revenue since their stream of revenue comes from context based advertising. Since Adblock blocks the javascript ads from Google it means that Firefox users with Adblock are less likely to be earning money for Google. I'm sure it would be trivial for Google to compute...but it would be very interesting to see stats for the click through rate dependant on browser type. I guess a popular site could compute the same figures which may be common across many sites to see who exactly (the type of user) that generates the most amount of money.
