If you use Delete browsing, search and download history on Firefox to clear the 'Browsing History' when you close Firefox then restoring tabs from the last session ("Save & Quit" or "Show my windows and tabs from last time") doesn't work.

I don't do that when closing Firefox.

This can be a problem with the file sessionstore.js and sessionstore.bak in the Profile Folder

Delete sessionstore.js and sessionstore.bak in the 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.

See:

• http://kb.mozillazine.org/Session_Restore

Did as above with sessionstore.js file. Also read and followed the instructions in the above article. Neither worked. Typically I click on the X in the upper right hand corner and receive the option message to Save and Quit or just Quit. I always click on Save and Quit and this always worked until recently. Anythiing else I should look at?

Are you using cleanup software like CCleaner that can remove the session history?

Do you see a file sessionstore.js in the Firefox Profile Folder?

Does it work if you use this?

Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"

OK, I fixed the problem. Don't know why it changed but it's no longer an issue. I went to Tools > Options > Privacy > Settings and unchecked Browsing History.

Thanks for the help.
