Attempting to open Firefox, before the window opens the crash report shows (and therefore I cannot try safe mode). I have updated Firefox, removed & re-installed, software & internet security & drivers are all up to date, no spyware or virus' have been detected. None of this changed anything. I have refreshed Firefox on one of the numerous crashes which led to the window flashing up briefly before crashing but ti does still crash before loading.
