YouTube Crashing

On a Rock64 running Manjaro/Plasma.
After the latest update.
Open Firefox, and go to YouTube, pick any video and the tab crashes. Sometimes freezing the system.

@strit can you check between
Firefox version compile & ffmpeg 4.4 versions ( it s going to version 5 )

Just like on x86_64, the ARM version of Firefox is built against ffmpeg4.4 it seems:

That’s on Unstable branch at least. The build on stable branch, should still be built against regular ffmpeg, which is version 4.4 in Stable branch.
