Hello. I have Mozilla Firefox and have been using for quite a long time. Recently I've had problems with my sessions crashing. When the option comes up to restore crashed session or last good session I choose the good session or I choose a completely new session normally. For the last week or so I've had an error pop up when I open my browser as well as anytime a new window opens for my browser. It reads:

Title: Session Manager Corrupted Data:
"Session Manager cannot load databaser from corrupted session.rdf.
The file session.rdf will be deleted, a copy can be found in session.old in your profile. Sessions backups are in <profile>/sessionbackups.

After I hit the continue button or X out of it my browser comes up fine and am able to "surf the web". How do I get rid of this pop up error??

Thank you for your time

Verify that the files you mentioned are deleted and also clear your history, cache and session info
