hi, thanks for providing some crash ids. unfortunately these crashes will be caused by websense security software running on your system and negatively affecting firefox.

according to some reports this might be fixed with newer versions of websense, so you might want to get into contact with your it department if they could roll-out an updated version of websense. otherwise firefox esr might also be an option: Old versions of Websense cause startup crashes in Firefox
