NoScript, but you can only control it per domain.

+1 for NoScript. It is kind of a pain for the first few days when you have to spend 10-30 seconds reloading sites to allow the minimum needed. It is also eye opening to see how much bloat is added and how fast pages load without all the extra bs.

		Thats my problem though, I don't want to have to allow the minimum for each site. I wish there was a noscript-like extension that used a public database of sorts to allow what's needed and block everything else, including things that are "needed" but suck so bad you shouldn't use the site
