Firefox opening two windows at startup
Firefox is now opening two windows at startup: one that has my previous session (which I always prefer) and one window with one blank tab. It used to open only the saved session. What can I do do change this. Thank you. (I have Firefox 122 version)

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.
- rename/remove sessionstore.jsonlz4
You may also have to rename the sessionstore-backups folder.
When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
