While I was reading more information about the recent launch of Google AdSense Referral program, I came across their November News bulletin which I will quote below:
Spread the word while increasing your earnings through referrals
With our new referrals feature, you can increase your revenue while increasing your users’ awareness of useful products and services. By adding a referral button to your site, you can direct users to sign up for AdSense and monetize their web content, or to download Firefox with Google Toolbar and improve their web browsing experience.
While your users learn more, you can earn more — US $100 for every new AdSense publisher who earns $100 and up to $1 for every new Firefox user.
You can begin referring users immediately – just visit the Referrals tab within your account, choose the product and the referral button you like best, and add the associated snippet of code to your site. Specific instructions for adding a referral to your site can be found here.
In bold, mine. I highlighted the new FireFox users part because it really got my curiosity there. Is Google planning on something that they’re willing to invest $1 for every new Firefox users? Some anti-M$ tactic perhaps? Interesting.


yes, that is available for US publishers only for now… i hope :)
