Can't restore previous session after restart and immediate crash - urgent!!!
Yes, it was extremely stupid of me to lose literally more than a thousand tabs containing really important research...How it all happened: I restarted my Mac and opened up Firefox to restore my previous session (like always), when FF crashed on me immediately, leaving the "Restore Previous Session" option greyed out. I just want to know what I need to do after I have moved and renamed one of my files (recovery.js / previous.js) to "sessionstore.js"...I tried opening the renamed file with my current FF version (57.0.1) and an ENDLESS list of links or something popped up in a new tab- and believe me, it would have took an eternity to scroll down to the very bottom. So then I compulsively quit FF and restarted..still nothing that can be restored....PLEASE HELP! :(

Sounds like that file is working if got a list of HTML though would think it is corrupted but recoverable with the info there and yes will take time unless........

If need help with any of the files and how to work with them ask, it will not be urgent as Support Volunteers around may not know the answers and will have to wait until someone is around that does.
Start on this info reading as will need to know what to do and what is being given in more info should you return.
I will escalate this though.
Please update to 57.0.2 https://support.mozilla.org/en-US/kb/update-firefox-latest-version
Please let us know if this solved your issue or if need further assistance.
Is there any way I can possibly separate all of the links from this list of nonsense?
Or... please tell me what I need to do after I have moved and renamed the file to "sessionstore.js"
Trying to get some one but is gone, maybe back later.
Do not work with the original Files, work with copies only.

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.
Please let us know if this solved your issue or if need further assistance.
Firefox 56+ releases compress the files in the sessionstore-backups folder and sessionstore.jsonlz4 with LZ4 (.jsonlz4 instead of .js), so it is no longer easy to inspect them.
Firefox can still restore uncompressed sessionstore files, but to make this work you need to remove (rename) compressed files and rename the sessionstore-backups folder to ensure that Firefox can't fallback to compressed .jsonlz4 files.
Make sure to use the correct file extension: sessionstore.jsonlz4 for a compressed file and sessionstore.js for an uncompressed file.
