I had two Firefox windows open. One with 100+ tabs and the other with 1 tab. I closed the Firefox with 100 tabs, and then closed the one with 1 tab, without thinking. I then realised that I should have closed them in the opposite order, because I want the 100 tabs to get restored.
I opened Firefox again and was dismayed to see just the single tab get restored. I did some searching and backed up the "sessionstore-backups" folder.
I then tried to close Firefox and replace sessionstore.jsonlz4 with previous.jsonlz4 from the backed up "sessionstore-backups" folder. This did not work, as when I opened Firefox I still only got the 1 tab back and "recently closed windows" remains grayed out. Ctrl+Shift+N does nothing as well.
I used https://www.jeffersonscher.com/ffu/scrounger.html to inspect the backed up previous.jsonlz4 file and it shows
Open Window 1
Tab 1 [...]
Closed Window 1
Tab 1 [...]
Tab 125 [...]
So the previous.jsonlz4 file does contain my mistakenly closed window but I can't get Firefox to restore the tabs!
Can anyone please help me get my tabs back? I'm on Firefox v96.0.1.
