Making FireFox more like OmniWeb
 

I don't know if any of you have to use a PC at work like I do, but here are a couple of extensions for FireFox (thankfully, I am able to use FF instead of IE) that I've managed to locate this weekend that adds session saving (almost Workspace like) features and a graphical tab sidebar:

Does anyone know of any better versions of these?
