Firefox isn't restoring last session, holding on to old closed windows...

I have my Firefox browser set to restore my previous session. However, when the browser crashes or my computer is turned off and then back on, it will only restore a single blank browser window. I know a fix around this, though - go to History and Restore Closed Windows. However, for the past three weeks, when I've done this the only windows that are restored are from my session three weeks ago - tabs that were closed get opened, and new tabs that were opened are now missing. Clearing my history and restarting my computer have not helped. Does anyone know why this is occurring and what I can do to fix it?

Thanks.

You can check for problems with the sessionstore.js file in the Firefox profile folder that store session data.

You can use this button to go to the currently used Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
