Over deze add-on
Session Manager saves and restores the state of all or some windows - either when you want it or automatically at startup, after crashes or periodically. It can also automatically save the state of open windows individually. The add-on is restartless and can be enabled and disabled on the fly.
This extension replaces SessionSaver and Tab Mix Plus' session manager. Session Manager is compatible with Tab Mix Plus. It can import sessions from both SessionSaver and Tab Mix Plus.
See http://sessionmanager.mozdev.org/documentation.html for the complete users and options guide.

POTENTIAL PROBLEMS AND SOLUTIONS:
1. WARNING: IF YOU ENABLE ENCRYPTED SESSIONS AND RUN CCLEANER DO NOT ENABLE THE OPTION TO DELETE FIREFOX PASSWORDS. DOING SO WILL WIPE OUT THE KEY3.DB FILE IN YOUR FIREFOX PROFILE AND MAKE IT SO YOUR SESSION MANAGER SESSIONS CAN NOT BE DECRYPTED!
2. Save button / menu item does not work and/or is grayed out - Likely your browser is set to "Never remember history" (i.e. permanent private browsing) history in the Privacy options. Due to Mozilla's policy that Add-ons MUST respect private browsing, Session Manager won't allow saving of private windows. This includes in backup sessions. Disable permanent private browsing and you will be able to save non-private windows again. If you don't like this, don't blame me, it's Mozilla's policy. See http://blog.mozilla.com/addons/2010/02/23/private-browsing-support-required-for-add-ons/
3. Recovering from a crash doesn't work - Crash recovery won't work at all if the user sets the option to never remember history or start up in permanent private browsing mode since no crash recovery data is saved by the browser. If you want to be able to recover from crashes don't set the browser to never remember browser history.
