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 or Tools menu > Add-ons

On the left side, click Extensions

Then disable as many as possible and restart Firefox.

Any luck?
