What's YSlow?
It's an extension to Firebug (yes, correct, Firebug, not Firefox) that helps with performance optimization efforts. It scores your page on the scale A to F, based on compliance with Yahoo's performance rules. It's a tool that has been used internally at Yahoo and is now released to the world.

Other features
Besides Performance, there's also the Stats tab which gives you comparison of how your page size for visitors coming with an empty cache vs the ones that have previously visited the page.
