Great idea and job. Very useful for me. I use session Manager, but each time I open FF, I need to wait that my 20 tabs loaded before I can began to work. Now, I just open the tab I want for reading and in background open the 19 others. So I keep session Manager+SessionPage.
Please update it for Firefox 3.5, It´s so useful.
