Just over a week ago, I found that a particular page transition always crashed by browser tab (i.e. a reproducible crash). This occurred on the Quora.com website when visiting the 'Questions' tab for any Quora Space. I am not aware of anything special associated with this operation, and it works OK in Chrome. There may be other cases -- outside of that particular website -- but that is the one most affecting me at the moment.

There are no associated Windows events logged. I checked about:crashes and the Crash Report folder but i cannot find any readable details.

If I refresh the page then the transition occurs without problem.

I would like to find the cause myself because I am on an Windows 7 64-bit ESR version, although I do not believe this is an ESR issue as it was working fine a couple of weeks ago. it is just that I cannot find any logged information on the cause.

Sorry, but I think I see where the details are now. I have to "submit" the report and the details are then visible at the bottom of the about:crashes page.

The details there lead with "Firefox 115.28.0esr Crash Report [@ JS::Heap<T>::exposeToActiveJS ]" which looks quite deep down, with many levels of crash thread.

It also occurred in Troubleshooting mode.

Since I reset my cache then it seems to have gone away.
