Since I didn’t recall downloading any huge files over the previous day or visiting any new sites that could’ve resulted in bringing down a lot of new content to the cache, this puzzled me. In my case, SSDLife notified me that 12GB was written to the SSD in one day. For those of you unfamiliar with this tool, it simply reports estimated lifetime for the attached SSD and it also shows the amount of data read and written.

You'll find that if you go onto the start menu, go to programs, Trusteer Endpoint Protection, and click on stop trusteer, Firefox will work fine. You're suffering from the same problem as myself, Trusteer Rapport is conflicting with Firefox 45.

Firefox 45.0 crashing
