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.
