The first time this happened, I tried closing Firefox and it crashed. This time I began closing each untitled page until the scrolling stopped, but I still have hundreds of untitled pages beneath the tool bar. Help

This can also be a problem with the file sessionstore.js and sessionstore.bak in the Profile Folder

Delete sessionstore.js and sessionstore.bak in the Profile Folder

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
