Session Manager 0.6.2.3

Session Manager saves and restores the state of all windows - either when you want it or automatically at startup and after crashes. Additionally Session Manager offers you to reopen (accidentally) closed windows and tabs. If youre afraid of losing data while browsing - this extension allows you to relax...
Using this extension you can always be sure that your current session will be saved the next time you open your Firefox browser.
This extension replaces SessionSaver and Tab Mix Plus session manager. It stores more data than both of them and should be more reliable in saving and restoring. Although it is not recommended to have more than one session related extension installed, Session Manager is compatible at least with Tab Mix Plus.

System requirements:
- Firefox: 2.0 - 3.1b1pre

Enhancements:
- The "Save Sessions..." menu item will now display all the time and the "Save Current Window..." will only display when there is more than one window open. This is the opposite of how it worked starting with 0.6.2, but was changed to prevent confusion. Functionally there is no difference since with one window open "Save Session..." and "Save Current Window..." do the same thing.
