Brak....thanks for the tip on Adblock. That was so easy a mod could do it! You choose is all gone and the nice thing about adblock is that you can JUST tell it EXACTLY the things you want to block and nothing else will get filtered. Very cool!
Yep, adblock is one of the best addons out there. Another one is flashblock - allows you to not run flash animations/ads etc unless you want them to run (click on the arrow in the middle and its on).
There are a few more, but those are for more hardcore privacy freaks like me
Cookie jar is one of those.
