[arch-general] Kernel 4.19 preventing Firefox from playing videos

[Frank Zimmermann]

Good evening,

I have a very strange issue with kernel 4.19.1 With this kernel Firefox
no longer plays any videos. It opens the page but the video wont play.
It gets even worse when I open another tab. This will freeze Firefox
though system load is ok. But I cannot kill Firefox, even logging off
and on will keep it running in the background. Only way to stop it is a
reboot and shutdown will take approx 10 to 15 mins for various stop
jobs running. just downgraded to Kernel 4.18.19 and things are fine.
I'm running Gnome on a Thinkpad X201.
