I enter a new session and it restores my last session after close. I tried all the stupid about:config stuff suggested in other questions and it didnt work. I have a homepage set. I have the correct session restore attributes set to false. I dont know what else to do. This is an annoying "feature"!!! Why do they have this????

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.

The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.


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

Windows hides some file extensions by default. Among them .html and .ini and .js and .txt, so you may only see a file name without file extension. You can see the real file type (file extension) in the properties of the file via the right-click context menu in Windows Explorer.
