I have lost the bulk of the Firefox Toolbar - all but those items in the Firefox Tab. When I try to close tabs the program closes and when I restart the tabs are still there. Do I need to delete and redownload?

Chosen solution

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).
