Someone recently mentioned a Firefox plugin that sounded interesting, I went to look for it and found a few good ones.
Browse Images is pretty cool, it'll open all the linked images on a page in a single tab. Nice for when you're looking at a lot of images (heh), seriously cuts down on the clicking.
There's a plugin for Bugmenot, I like that too.
formatting link
has a bunch, they're easy to get elsewhere too.
And if you're still using IE, give Firefox a try.
