3. Waterfox Classic 2020.03.1

Expected

• in Waterfox Classic, a prompt to allow use of a microphone

Actual result

• process crash (reported in Reddit) or system crash (reproducible here).

I can't reproduce that, but I didn't checked on latest Windows 10 build.

Thank you, also I should prefer to check with a physical machine running Windows 10. (Not easy for me to do so, given the restrictions that are associated with COVID-19).

It's vaguely possible that the system crash behaviour occurs only in VirtualBox (5.2.34 r133883) on a FreeBSD or FreeBSD-CURRENT host, however in my experience it's extraordinarily rare for a guest machine to crash in this way. Something smells not quite right.

PS I do have remote access to a physical machine running Windows 10 but there's no microphone; I'm unable to test.

Also:

• FreeBSD bug 245641 – emulators/virtualbox-ose guest crashes whilst running some types of application with webcam or audio input on USB

All things considered, I'll close this incident. It can be reopened if necessary.
