I have a large number of tabs open. I have tried closing a lot of them but whenever Firefox restarts, it reopens ALL the old tabs, including the ones which I closed individually during the previous session, ie it ognores the fact that I specifically closed some of the in the previous session. I need to reduce the number of tabs substantially but Firefox is preventing this. I am NOT a technical expert. Thanks to anyone who can help.

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.

  • rename/remove sessionstore.jsonlz4 and sessionstore.js

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).
