How do I get my tabs back into the main window?
I've had a problem with an add-on displaying a small extra window every time I open a session for some months now: I know you're supposed to try disabling and re-enabling every add-on you've got to find out which one is responsible, but this is a work computer and with all the add-ons I have, it would take too long, so I've just closed the extra window every time and got on with my work. However, for some reason today my forty-odd tabs have all opened in the small extra window, which has no tab bar, navigation bar or menu button. How do I get my tabs back into the main window of Firefox, or alternatively get that window to behave like a normal Firefox window so I can use it?

Tried closing everything, with the problem window last of all, to see if it would reload as a normal window. It said it was closing 43 tabs, but again it opened as the useless window, with all the tabs stuck where I can't get at them - and a succession of pop-up boxes saying 'overlay:page_load missing' for every single tab.
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 file and possible sessionstore-##.js 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).
You can use this button to go to the Firefox profile folder:
