Last time also about 15 days back same thing had happened, I had uninstalled it, asked for help from your end and had got it fixed.
But doing it every time, especially, when one has to do many things on line, is not possible.
Pl suggest some long lasting solution.

Answer 1

By the way, the "faulting module" listed in your crash data is not part of Firefox. According to some other posts, it actually is malware named SProtector that you need to remove. Please see:
