Rated 5 out of 5 stars

Updating from Firefox 3.6.2 to 3.6.3 broke this add-on. Adore this add-on.
FIXED per support site info - First FF popped up saying that the Java Deployment Toolkit 6.0.1.190.4 was buggy and set itself to Disable - which I did and restarted FF. Don't know if this has anything to do with problkem or fix, but I did it first. Then - Uninstalled Session Manager (It keeps all old saved sessions intact - i.e. they DON'T get deleted) - Restarted FF. Then reinstalled Session Manager 0.6.7.4 from the Mozilla Add-on site here, restarted FF again and - FIXED. All better now. Working just fine.

This review is for a previous version of the add-on (0.6.7.4).
