I admit, I was disappointed that the Firefox referrals program was limited to US publishers only when it launched on November 4th. But looks like they have listened to publisher feedback and have now rolled it out to all international publishers.
International publishers can now refer users to Firefox plus Google Toolbar through the AdSense referrals feature. As you connect your users with Firefox to improve their web browsing experience, you can generate earnings – up to US$1 for each new Firefox user who downloads and runs the product for the first time. To add a Firefox referral button to your site today, visit the ‘Referrals’ tab in your account.
Many international publishers were upset that AdSense originally restricted it to only US publishers, regardless of where the site’s traffic was from. So it is nice to see AdSense make it available to all.
