If you are a Firefox user - and most Adsense publishers tend to prefer browsing with Firefox - you may have encountered problems logging in to see your Adsense stats recently.  Publishers reported to Google that they were not seeing their usual login page, and it appears that the culprit may be a Firefox extension called Adblock plus.  If this is happening to you, here is the way to dela with it, direct from the Google hub: clear your cache and cookies and turn off the Adblock software before trying to log in at www.google.com/adsense.
