Greetings, firefox is seemingly random unable to detect the Pulse Audio Software on my pc. Therefore I am unable to get sound output for example on youtube.

However, a restart might fix the issue, but in some cases several restarts do not help.

Running firefox from the command line results in the following output, simultaneously with the error: fork(): Operation not permitted [Child 2702, MediaPlayback #2] WARNING: 7fcd0118d580 Can't get cubeb context!: file /build/firefox-9j9NY8/firefox-58.0.2+build1/dom/media/AudioStream.cpp, line 358 [Child 2702, MediaPlayback #2] WARNING: Decoder=7fcd040c9a00 [OnMediaSinkAudioError]: file /build/firefox-9j9NY8/firefox-58.0.2+build1/dom/media/MediaDecoderStateMachine.cpp, line 3642
