Bitdefender Free crashes Firefox 56.0 64bit on Windows 10.
I tried restarting Firefox in safe mode, disabling all plugins, factory reset, uninstalling and starting with a clean environment. In whichever scenario I tried, Firefox was running for about 2 minutes and then it became unresponsive, but hogging CPU time.
Turning off Bitdefender Free Protection Shield made all the crashes go away.
