Faulure to Restore Previous Session
I lost a session with several open windows, and very valuable tabs. No idea why, Session Restore has been working well for months, and I restart frequently. Under History, Recently Closed Widows' is greyed, when 'Restore Last Session' is shown, (Forget how I got that, it's disappeared again) it's greyed too. Open Previous Windows was/is enabled under Startup in Preferences. Mac Mini, late 2012, up to date Firefox, 109.0.1, macOS 10.13.6 Safari window did Not disappear, it restored properly. Which it has been doing regularly, same as Firefox. I only struggle with Safari because streaming TV on the net (spectrum) works better for me on Safari, as do Imgur front page memes.
