I have problems restoring tabs and saving pin apps with Firefox 5 on Mac OS X version 10.6.7

I bought a Macbook Pro a few months ago and since installing Mozilla Firefox on my system, I have never been able to restore previous sessions after closing Firefox. I currently use Firefox 5 and I've tried pinning open tabs as apps tabs but those too disappear when I restart Firefox.

I use a few add-ons including DownThemAll, Force-TLS, Rikaichan and Rikaichan's Japanese-English Dictionary File.

App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the Firefox profile folder.

Make sure that you do not use Delete browsing, search and download history on Firefox to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.



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).
