NoScript

On my laptop, I use firefox and an extension called NoScript.  What NoScript does is blocking general javascripts from running.  Apparently, it whitelist itself so that Ads that require javascript on its own website can run.  Not only that, it went further by tampering with another Firefox extention called Adblock Plus so that Adblock Plus would not block NoScript's Ads.  Here is the apology letter sent out to the Mozilla Community by Noscript author.

Anyway, I do recommend this extension if you have firefox.  But go ahead and modify the default whitelist once you install it.
