After a windows update yesterday, when I started Firefox it didn't load my previous session as usual. Previously, I've been able to go to settings and restore the session, but there were no options for that and the relevant session wasn't shown in the recently closed tabs or windows, even though the history was intact. It loaded a new/blank window, and since then when I close and either re-open or try to restore a previous session, it only opens the tabs that I've opened today.
Firefox 118.0.2 (64-bit), Windows 10 PC.
Here are the steps I've taken:
- Turned off the "Open previous windows and tabs" in the startup options to get access to the "restore previous session" option
- Gone to the profile folder and copied, then removed the contents of the sessionstore-backups folder
- Copied the relevant backup session file (looks like it has the tabs I need when I scan it) to my desktop and renamed it "sessionstore.jsonlz4"
- Replaced the existing "sessionstore.jsonlz4" file in the root profile folder with the new one from my backups
- Reopened Firefox
It still just loaded my tabs from today, and doesn't show the session I'm looking for in recently closed tabs or recently closed windows. When I go to about::sessionstore, it says it's having trouble getting my tabs and pages back, and there's no option to reload a session.
I checked my sessionCheckpoints file in my profile root folder, and it only had these values:
{"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true}
I updated it to include these values and restarted again, but the result was identical:
{"profile-after-change":true,"final-ui-startup":true,"sessionstore-windows-restored":true,"quit-application-granted":true,"quit-application":true,"sessionstore-final-state-write-complete":true,"profile-change-net-teardown":true,"profile-change-teardown":true,"profile-before-change":true}
When I open the sessionstore.jsonlz4 file in Notepad++ I can read it normally, and when I just double-click to open it in Firefox it appears to parse correctly in terms of both structure and data... the tab 0/entry 0/URL shows the URL of the first tab that I had open, tab 1/entry 0/URL shows the URL of the second tab, and so on. So it looks like the data is there, but I can't seem to force Firefox to load that.
Any suggestions for what I'm missing?
