To the best of my knowledge this is only an issue with Peppermint 6 and Firefox 50.

FF 50 users will notice the following warning on many websites: "libavcodec may be vulnerable or is not supported, and should be updated to play video."

What it means: Libavcodec versions older than 54.35.1 will be blocked by Firefox due to security concerns. Ignoring the message will sometimes work, sometimes not.

How to fix it:

Open Terminal and type the following commands:

Code: [Select]
sudo add-apt-repository ppa:heyarje/libav-11
sudo apt-get update
sudo apt-get install libav-tools
sudo apt-get upgrade

Press 'Y' (Yes) if the installer asks you about replacing old files.

A reboot is recommended afterwards.
If you like Linux, raise your hand. If you don't, raise your standards.

In addition to Capivara:

If you can not update to a newer version (dependencies), type "about:config" in the url bar and search for "media.libavcodec.allow-obsolete", right click on it and choose "Toggle". This will set the Value to true. Restart Firefox, it will now use the old libavcodec-version without protesting...
