So I've always had about 10+ tabs open and every time I would close my window, and open back, they are all still there. Recently, when I closed my Firefox window it would just open back to my homepage. I've already went to options>general> and did the keep tabs open thing, but it doesn't work anymore

You can also check for issues with session restore.


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 file and possible sessionstore-##.js 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).
