Thank you for your help.

thanks, this kind of crash appeared to be happening while an automatic update is in progress and parts of the application are already up-to-date, while some running processes are still from the old version. this will be fixed in firefox 62 and onwards - in such a situation a user will get a note to restart the browser to fully apply the update.
