For those of you using adsense for your sites outside of the U.S. I’ve just read that adsense firefox referrals are now available internationally. This is coming from the official Google adsense blog. The referral program was opened up in the last month offering site/content owners to add referral links into their content alongside the traditional ad blocks, or ad links. The rollout of the referral service was initially in the U.S. for Firefox referral’s. Google also launched referral links for it’s adsense program. The payout varies for each program, but the Firefox referrals can pay up to $1 each.
