FireFox wont restore sessions from sessionrestore.js, only .sonlz4. Help
today on July 12th I opened FireFox and it erased my entire previous browsing session, why?
I will never know, however i had a backup from July 1st.
Yay, right? I could just restore the July 1st one right?
Well I followed the available instructions and deleted all the .jsonlz4 files, renamed sessionstore.jsonlz4 to sessionstore.old and renamed upgrade.js-20170628075643 to sessionstore.js as most instructions I found told me to.
Then I opened up FireFox but to my dismay it didn't restore my previous browsing session that from the new sessionstore.js file.
It created a new sessionstore.jsonlz4 file and completely ignored the .js sessionstore file?!
I so thought "Maybe I should just replace .js to .jsonlz4 and everything will work out fine right?" Wrong, when I changed it from sessionstore.js to sessionstore.jsonlz4 it did load some of my previous browsing history but ignored most of it!?
Whats going on!!!!

Look on Your Desktop for a Folder called OldFireoxProfile Let us know.
Hi Dafox, sessionstore.js was obsoleted with Firefox 56 so I don't know why you have one from July 1st. Unless it's July 1, 2017.
Anyway, I think the larger issue is that Firefox 56-61 are likely to exhaust the other available files first, so you need to hide them. Could you take a look at my lengthy reply in this thread:
All tabs lost after upgrade from FF 56 to FF 61, I have sessionstore.js, it is ignored.
Note that you need to place the renamed sessionstore.js in the main profile folder.
Did you rename the sessionstore-backups folder as well?
That upgrade.js file is from last year June (20170628) and may not be compatible with current releases.
Don't you have a more recent upgrade file?
