Other users have reported that this is caused by one of their add-ons. I suggest going to the Add-ons page and disabling everything that is not essential, and then restarting Firefox. Hopefully it's not caused by something you really rely on.

orange Firefox button > Add-ons > Extensions

or

Tools menu > Add-ons > Extensions

Any luck?
