Firefox 4.0.1 closes with no error message. When I restore the session I get: Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page. What can I do?

After opening certain websites, pogo, firefox 4.0.1 closes with no error message. When I restore the session I get: Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page.

I have had this problem before and had to reinstall an earlier version of firefox.

The error console has a long list of errors, many of them end with: does not implement nsIObserver. Is there a way to send the information on the error console to firefox support?

Redownloading Firefox 4.0 will fix my problem until I either close firefox or turn off my computer. The problem recurs when I open firefox again.

See:

It is also possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Profile Folder

Delete the files sessionstore.js and sessionstore.bak in the Firefox 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.
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).
