Firefox will no longer connect me to the internet. I can connect to the internet using Internet Explorer, but not Firefox. Prior to this problem my McAffee security was giving a message that a Firefox program was trying to run but McAfee didn't recognize it. I chose to block it from running since I didn't know what it was. I have uninstalled Firefox and tried to reinstall Firefox from the download link at Mozilla.org. This did not fix the problem.
