Hi there, I'm running Firefox (136.0.1) on my mac laptop (MacOs 15.1) Just recently it has started silently failing. I move away from the window and after a short period (hour or so) I can see it is no longer running. When I start it again it offers to recover the session for me. I've tried checking about:crashes but it just says no crash reports have been submitted. There are no details of unsubmitted reports. Thanks, John
