Can not close tab
I browsed a dozen sites and FF got slow, then I accidentaly double clicked a grey background next to an open tab and it opened a new tab. I tried to close it but this message appeared:

I can't close it and can't close any tab.
It happened once but slow-downs happen everytime I open firefox! 10.0.2 installed!

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
