Tor Browser won't run from inside its DMG
I have downloaded Tor and tried to open it several times. However, each time I attempt to do so, even after restarting my computer, I always get the following message - "A copy of Firefox is already open. Only one copy of Firefox can be open at a time." Yet, I do not have Firefox open.
Matt Pagan from your support has kindly and patiently assisted me. I am using Mac OSX 10.9.3 and I have Norton Antivirus. I have changed the settings in my System Preferences to allow other applications and downloads from the Web to open, as well as changing my Firewall settings, but no success.
