I am running Firefox 5.0. Just recently, it started to open multiple (over 10) windows when I start it from the quick start area. All of the windows open with a single tab entitled "New Tab". Any tabs that I had open from my last Firefox session are ignored. I've used Firefox for many years. I use a desktop running Windows 7 SP1 Professional with an Intel i5 chip.

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 files sessionstore.js [2] 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 and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

I'm logged in, but I cannot see "Solved It" anywhere on the screen. All I see is "Solution chosen" under cor-el's post.

I'm sorry I didn't see the "Solved It" choice yesterday. This is my first time on this forum and merely wanted to thank both of you for taking the time to help me.
