I have been using Firefox for a good number of months, but in early January it has ceased to open? I have updated and to the newest editions, but it will still not even open when I click on the the Mozilla Firefox button?

I cannot get Firefox to open on my CP. I have had to go back to Internet Explorer to get on the Internet.
