so i just started up my computer, and i have the start up preferences set to restoring previous session. this usually works out just fine, even when firefox updates. however, this time (for the second time all around) it didn't go right. for some reason, the tabs opened up are from over two months ago from june, rather than my previous session. this is the second time something like this has happened to me.

i checked my homepages, and the alternate profile, and both seemed normal. (the homepage is the firefox home and the alt profile is the bare, the profile before i imported my bookmarks, passwords, add-ons, etc etc) reopening my previous tabs hasn't been too much of a hassle, but i don't want to make a habit of this. i have very limited technical acumen, so please be detailed and specific in your reply, i do genuinely need my hand held here.

if you have any more questions for me i'm happy to answer. thank you in advance!

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).
