Azoogle is a great CPA network. If you haven’t already heard of them, give them a try.

If you already have an account with them, and missed the announcement, check out the Azoogle Toolbar for Firefox and IE. You can contact them for the beta release.

I just installed it with the latest version of Firefox and it looks good so far. Clicks, leads, payout & eCPC at a glance, similar to what Adsense Notifier does with Adsense. You can also set it to display monthly or daily stats.
I have a bunch of other extensions installed, none of which seem to conflict with the AzoogleAds Toolbar.

Nice work, Azoogle!
