Since we launched referrals last week, we've received a number of publisher questions about this new feature. So, we thought we'd clarify a few of the top issues that we continue to see:

Will Firefox plus Google Toolbar referrals be made available to publishers outside the U.S.?

Currently, Firefox plus Google Toolbar referrals are only available for U.S. publishers. However, we're continuing to improve the referrals feature and hope to make Firefox referrals available to international publishers soon.

UPDATED: Firefox referrals are now available internationally.

Can publishers use language endorsing AdSense or Firefox plus the Google Toolbar (e.g., "I use Firefox with the Google Toolbar and recommend it to other web users")?

Including such language is fine. However, as with AdSense for content, publishers should not use language encouraging clicks on your referral buttons (e.g., "Click here", "Visit these links", etc). The AdSense program policies is the best place to find more specific information about referral policies.

What happens if a user who clicks on the Firefox referral button already has Firefox?

In this situation, the user will be redirected to the Google Toolbar for Firefox page. Because we only count referrals for Windows users who have not previously downloaded Firefox, this will not appear as a Firefox conversion in your reports.
