Is this the area for questions about the old Safari Extension?

Safari crashed the other day and when I try to reload all the pages from the last session in History it starts and then crashes the finder. I still have the old extension version of SR running, but that isn't having any more luck. I didn't have autosave on but SR shows all the URLs from my last session, but I can't find a way to capture those URLs. If I chose to save session it says no pages to save. Is there a way to capture the last session information? I'm on Safarl 12.1.2, MacOS 10.14.6

@gephoto I'm on version 8.0.3

Safari keeps crashing the finder when I try to reload the last session. Where can I find the info on the last session (it wasn't saved)? If I try to save now it says there's no data.

I'm on an older version. Will installing the newer version help?
