A great, effective extension with a clean, intuitive design. I don't understand what the negative reviewers were complaining about, as I've found it easy to use and quite reliable.

The developer obviously studied the GUIs of other well-designed apps. TSM has lots of great features (I particularly appreciate being able to select how many automatic backups to maintain), but it avoids overwhelming you by keeping them in logical places you can access as you wish.

Before I returned to Firefox (when it got fast again), I used the Session Buddy extension with Google Chrome. There's just one thing I miss from it: Sometimes I save sessions I need to remind myself about later. Session Buddy showed the session list as a full page, so I could leave it open when I closed the browser, and it automatically restored itself the next time. By contrast, you must click TSM's icon to see the session list—so you have to remember that you _should_ see the list. :?) It'd be great if TSM included an option to show it as a regular, restorable page.
