I have a Macbook Pro I purchased new this summer (2014). I installed the latest version of Firefox in July 2014 and it worked fine for over 2 months. Suddenly, Firefox no longer opens. It flashes like it's opened a window but nothing shows. I created a new user profile and it worked fine on the new profile, and gradually Firefox is having the same problem on each user profile I create. Please help!
