I had like over 100 tabs lol but I had a Windows Update. My laptop froze while I had Firefox open. After the laptop restarted, I realized the new patches didn't get applied before Windows started up again, so after Windows started back up, (I did not open Firefox at all during this cycle) I went to Windows Update and hit Restart to apply the updates. After the updates got patched in and Windows restarted, I went to open Firefox and it just opens the home page. I do have Restore Previous Session upon Startup checkmarked. Tried restoring from the 3 line Menu button but the Restore option is not there. Did try under History in the Menu bar but my Recently Closed Windows and Recently Closed Tabs are greyed out. Tried the Library icon's Recently Closed Windows and Recently Closed Tabs within History and they both show up as (Empty) Went to my Profile's folder into the sessionstore-backups folder and there's only 2 small 44kb files there both that were created when I started Firefox up: recovery.baklz4 and recovery.jsonlz4 ... the sessionstore-backups folder itself was also created when I started up Firefox after my Windows Update. I read thru stuff like https://support.mozilla.org/en-US/questions/1204253 I do not have any files that have previous.jsonlz4 or upgrade.jsonlz4 like mentioned in my sessionstore-backups folder... not sure if they may be somewhere else like in 1 of the Temp folders somewhere else in Windows folder. If I uninstall last Windows Updates, would it revert my Firefox Profiles folder to what it previous was or does Uninstalling last Windows Updates have no effect on the Firefox folder?
