Rated 4 out of 5 stars

I'm using Version 0.3.8.1 with FF 2 portable. I like it for the most part BUT:

The session manager is flawed. Even if I open a new window and restore a session, it closes the other window with all the open tabs and replaces it with the new window with the restored session. I lose all my current tabs that took so long to find and open. Really unacceptable. Sure I can first save the current session but the first time I didn't think I had to and why put anyone through that?

Also the background colors for visited/unvisited tabs do not work.

Maybe this is fixed for the new version but I can't use it with FF 2.

This review is for a previous version of the add-on (0.3.8.2).
