Human nature, I suppose. But sorry.

Anyway, the reason that I'm here is that I am using Firefox 3.0.6 with your add-on and it was working perfectly until yesterday (or the day before, depending on which timezone you live in).
Then all of a sudden I was browsing Facebook and the adverts started appearing after months of successfully being blocked.

I can manually filter most of them out, but
http://apps.facebook.com/advertising/?src=advf2
just won't go away.
It's no biggie, but I thought you would like to know.
Cheers, Will
