Get the extension called adblock!

Everytime you see a banner, bring up the menu, find a word in the banner that refers to the company and type it in * is a wildcard.

So:

*doubleclick*

and you'll never see anything from doubleclick ever again! No banners, no popups, no nothing! Completely blocked!

If anyone uses adblock, I have a pretty good list I'd be willing to share.
