Debugging crashes

I’m trying to debug a Tor Browser crash in my Selenium Tor project. Firefox has a facility to debug crashes using a minidumps directory in a temporary user profile and also an about:crashes URL for viewing crash reports if the flag --enable-crash-reporter is set (added in the latest version of geckodriver). Neither of these features appear to be enabled in Tor Browser (the former is empty after a crash and the latter URL appears to be disabled in TB).

Is it possible to enable them? Many thanks in advance.
