Not seeing the sponsors at the top of the page, are they gone?

They're appearing just fine for me.

Install any new software lately?

No, hmmm thats wierd. What could cause that?

Firefox with adblock makes just about all banner ads disappear.

This computer does not have anything than what It came with last year. I have not added, erased or changed anything since I got it. The only thing I do with it is Ebay and TGO. I know very little about computers or how to fix it so any Ideas?
