Firefox 50.0 will not start with McAfee Firewall Turned On
I am having issues where my Firefox will not even open at all.
The application crashes and shows an event in the event viewer as attached.
The event is:
Faulting application name: firefox.exe, version: 18.104.22.16852, time stamp: 0x581d78ba Faulting module name: HcApi.dll, version: 22.214.171.12453, time stamp: 0x570e61e2 Exception code: 0xc0000005 Fault offset: 0x0000cc18 Faulting process id: 0x1cc0 Faulting application start time: 0x01d24981a551e219 Faulting application path: C:\Program Files (x86)\Mozilla Firefox\firefox.exe Faulting module path: C:\Program Files (x86)\McAfee\Gkp\HcApi.dll Report Id: 960b12ee-1934-47b5-8390-3745a2595c6f Faulting package full name: Faulting package-relative application ID:
Basically if I turn off my firewall in McAfee Security Centre, Firefox will open perfectly normal.
Not sure if this is an issue with McAfee or FireFox but I think it's still relevant.
I'm on Windows 10 with the Anniversary update and both McAfee and Firefox are fully up to date as well as Windows.
