Rodrigo writes about a new tool that resides at the bottom of the Firefox browser and can check on Google Adsense statistics such as the number of your Adsense ads, clicks/page view, eCPM, and the revenues you're making from the program.  The gizmo is called Adsense Notifier and you can get it from this link.  As a bonus, you can also get GMail status from the same site (called Mincus code).
