FF opens 19 instances, but loses tabs
Firefox is operating strangely. I recently updated to 5.0.
Now, I use FF with several add-ons, including Too Many Tabs. When I closed FF last night, there were 5 tabs, plus a total of 31 tabs in 7 TMT toolbars. I closed FF normally.
When I ran FF this morning, it opened 19 instances of Firefox. All of them had all the TMT stuff, but opened with a New Tab only -- that is, the 5 tabs that I had were lost.
I think that this is a FF 5 problem, as this happens every day, and I didn't have this problem before, but I don't remember when it started.
Can I go back to FF 4 series? Where can I get it? Will I still have all my TMT tabs?

Does this happen after disabling all your add-ons? Some add-on might be causing trouble with the new version but do not worry, in such case an update for the add-on would be available soon. I do not recommend rolling back to Firefox 4.0.1 as Firefox 5 is a security update for Firefox 4.
I've been reluctant to try the "disable all ad-ons" selection because I was unsure if I would get all the data back after I re-enable. Specifically, I don't want to lose all those Too Many Tabs tabs.
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 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 all open tabs to get lost, so you will have to create them again (make a note or bookmark them).
See:
There were a whole bunch of files sessionstore-##.js and I deleted all of them. I haven't done anything else yet. but that might have done it. I'll post again tomorrow, but I left three tabs open, and Firefox reopened with them, and only one instance of Firefox.
