Since last week, I'm receiving the following message for almost every page that I open in Firefox:
libavcodev may be vulnerable or is not supported, and should be updated for play video
Apparently, this is just a warning, 'cause I can play videos normally.
sudo apt-get install libavcodec
but this package does not exists.
I also did
apt-get update and
apt-get upgrade, but the message persists.
Finally, when I use
apt-get autoremove, it does not return any package.
I googled for the message, but not found anything similar.
What should I do to eliminate this message? Should I stay alert for anything?
