thank you for following up. unfortunately those crashes appear to be caused by trusteer rapport which is running on your device and hooking into firefox - please check that you are fully updated there or temporarily disable/uninstall that software for the moment.

please also get in contact with trusteer's support which are usually very quick to respond and fix issues like this: https://trusteer.secure.force.com/PKB/articles/en_US/FAQ/browser-crashes

Thanks so much, I will get it sorted now.
