I had Firefox and it crashed. It would never launch again. I then removed it from my laptop and restarted. I then downloaded it again. Same results. What is going on? Today I downloaded again and it launched but now when I open my computer again, it will not launch.

Will Firefox start up?


Sometimes a strict "program control" firewall or malware will stop Firefox from running. You can investigate these possibilities further using the steps/tools in these articles:
