How can I keep firefox session manager from being deleted?

[tandsoxie]

When I empty the my sandbox, I can't recover my sessions when I open Firefox or Seamonkey again.
It seems to delete those, too.
What's the securest way of allowing session manager files to be kept?

Thanks a lot.

You can do that in Sandbox settings>Applications>Web browser>Firefox, tick the option to Allow Direct access to Firefox session management.
