How do I make Firefox stop loading old tabs each time I start up? In options the startup says "show my home page" but I still always get the old tabs. I am running Windows 7 and Firefox ver 19.0.2.

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.


You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.

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).


Make sure that Firefox closes properly and that there isn't a hanging Firefox or plugin-container process left in the task manager.

Use "Firefox/File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit") to close Firefox if you are currently doing that by clicking the close X on the title bar.


If you do not keep changes after a restart then see:
