Public bug reported:
In Xubuntu Firefox does not play videos of e.g. YouTube or the Dutch TV
Viewer. It works in all other Virtualbox VMs with e.g. Ubuntu 20.04,
Ubuntu 16.04 or Windows 10 Pro. The problem is related to the buffering
(stats for nerds). It build up the buffer and when the buffer reaches
its value, it plays the content of the buffer in a few milli seconds.
Afterwards it starts again with the same process.
I have reinstalled firefox, but the problems remains (apt --reinstall
install firefox)
The problem is independent on the selection of the hw acceleration in
the firefox preferences.
