In browser GM Tools

I like to GM from inside Firefox and I was wondering if anyone had suggestions on sites to use. I have found a few sites so far but was hoping some one had some more ideas!

This one seems useful but a touch lacking in features. I like that I can import URLs and minimize the number of tabs I have to have open.

This roller lets me save rolls.

GMs, what if any browser based tools (or addons) do you use?

This website (http://www.d20srd.org/) has a lot of good stuff, including an encounter calculator and a monster filter.

Have you looked at Chaotic Shiny (http://chaoticshiny.com/)? Lots of useful generators for when the party takes the option marked "None of the Above."

I think I am going to try Combat Manager, unfortunately I use linux so I am going to try and run it in an XP VM.
