Sometimes all of my tabs suddenly turn into new tabs, this happens when I've previously closed the window page and then reopened it. How can I get all my tabs back?

Hi There,

To restore your most recently opened tabs:

History Menu -> Recently Closed Tabs -> Restore All Tabs

Hope this helps!

Do you mean that APP tabs are changed to normal tabs?


Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).


It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile Folder.

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).
