Firefox will not start after updating
•If Firefox fails to start after an update, first check the Latest Firefox issues article to see if it contains a solution.
•If you use certain versions of ZoneAlarm or other Internet security software that includes a "Virtual Browsing" feature, it can prevent Firefox from starting. Check virtualization settings and clear the virtual cache, if your Internet security software includes this feature, or visit the software provider's support site for more help.
