Rated 4 out of 5 stars

So many times I had accidentally closed not just a tab, but a whole window of tabs, by mistake. Session Manager to the rescue, a quick undo or restore of one tab or a whole window of tabs is easily done. Additionally, the ability to save an entire session (all windows and tabs) is a nice tool that I sometimes use in cases such as the following: I have a bunch of FF windows/tabs open, but for memory/speed purposes I want to close them while I work on some other CPU/memory intensive stuff for a few hours while still leaving FF open for minimal browsing services --- now I can do this by saving everything as a named session and closing all the windows, and then later restore the named session.

This works great, and doesn't conflict with my other tab extensions (Taboo, ColorfulTabs, LastTab).

WISHLIST: As someone who uses two computers at home, plus a laptop while traveling, it would be nice if there were an option for "remote" storage of a session. There is a Firefox add-on called Linkwad which does this, and it would be really nice if Session Manager could build Linkwad style functionality into it (I would rather have a single extensions, Session Manager, that handles all of my session storage -- both local and remote -- rather than having to deal with two different session managers, which complicates things a bit).

This review is for a previous version of the add-on (0.6.1.5).
