Firefox no longer able to play videos on Facebook

Show all headers | View raw

Hi,

Until a few days ago, Firefox played videos on Facebook without issues, 
but now it cannot play the same videos anymore. It may coincide with me 
installing and uninstalling some Industrial Camera software (the only 
major change I remember doing in the meantime). It included make 
install, but I thought I got it cleaned up fine...

I've tried to reinstall Firefox, *codec*, *plugin*, *pepperflash* and 
some other packages, and tried to disable hw-accel in Firefox, without 
any change in luck.

I know it's hard to tell what went wrong, I'm also aware of the 
problematic deb-multimedia, but perhaps you guys can help me find out 
where to punch the system to get it to work again?


Facts:

1) A few days ago Firefox played FB videos nicely.

2) Now Firefox console says (tried a few videos):
Error: The manifest specifies content that cannot be displayed on this 
browser/platform.  5-rDEXaxCbl.js:393:371
The video on this page can’t be played. Your system may not have the 
required video codecs for: video/mp4; codecs="avc1.4D401E", video/mp4; 
codecs="avc1.4D401E", video/mp4; codecs="avc1.4D401F", video/mp4; 
codecs="avc1.4D401F", audio/mp4; codecs="mp4a.40.5", video/mp4; 
codecs="avc1.42E01E mp4a.40.2", video/mp4; codecs="avc1.4D401E 
mp4a.40.2", video/mp4; codecs="avc1.4D401F mp4a.40.2", video/mp4; 
codecs="avc1.640032 mp4a.40.2", video/mp4; codecs="avc1.640033 mp4a.40.2"

3) Youtube plays fine both before and now.

4) I downloaded the FB Video with youtube-dl and played the video 
through Nautilus on VLC and Totem without problems.

5) Fully upgraded Debian Buster/Sid - Linux 4.18.0-1-amd64 #1 SMP Debian 
4.18.6-1 (2018-09-06) x86_64 GNU/Linux.
