Can't turn off add
 

For some reason the tornado add in the corner of the screen is back and I can't turn it off again. I had successfully turned it off a few weeks ago. I went to the link that Mantalope provided and it says that it has been succsessfully disabled but it still there.

HELP!!!

Edit: I clicked on the add and selected turn off forever it worked until I changed pages. The add is back again.

I just let it stay there and played with it from time to time. lol.
I only found it a bit annoying.

Install NoScript firefox addon and AdBlockPlus. It will take off a lot of the troubles you might get on some webpages, but you need to make sure to enable some script you actually need on some webpages.
