I have been using Firefox for a very long yime and this is the first time I have encountered this problem. For some reason, i am unable to start Firefox and it does not show up in Task Manager. I have the latest version and I have un-installed and re-installed 4 times with no change. I click on the shortcut icon for 30 seconds straight, still nothing. I just want to know if anyone has this problem and/or can someone help me.
