@SweetP I would say it's better. I'm not keeping track of time Safari is up front but sometimes I just leave the Safari screen up for an hour or two yet nothing is saved. So it's unpredictable but, yes, I AM getting occasional saves, which is probably sufficient.

Perhaps when a screen saver kicks in Safari no longer is seen as active?

@SweetP A session was just saved, 24 hours and 5 minutes since the last one!

@SweetP Thanks, Russell. Unfortunately, I can leave Safari upfront for hours yet the session won't save. It's been over 22 hours since the last save. I'll try not to restart anything in case there's info you need.

SessionRestore 2.7.3 only seldom saves sessions for me. Last save was about 23 hours ago. The time before that, about 8 hours earlier. Granted, this is under Mojave so the situation may be different than other reports. Please let me know if there's something you'd like me to do to help track it down if Mojave is still supported.
