When I open Firefox it opens additional windows

Since I installed version 5 of Firefox when I open Firefox, it opens a window with all the tabs that I previously used correctly but it opens also several additional browser windows, with a single tab and a vacuum. I tried to uninstall Firefox and install fresh but which did not help. At the present time 30 additional browser windows are open when I open Firefox!

Any suggestions?

It is possible that there is a problem with the sessionstore.js and sessionstore.bak files in the Firefox profile folder.

Delete the sessionstore.js and sessionstore.bak files in the Firefox profile folder.

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

Delete sessionstore.js will cause App Tabs and groups of tabs and all tabs open to get lost, so you will need to create them again (take note or bookmarks).
