Why doesn't OpenH264 get installed?

Hi Mozilla Community,

I recently deleted Firefox and reinstalled it for some troubleshooting, and now I am facing an issue with the Add-ons. It now says "Will be installed shortly" for about 2 days already for the add-on "OpenH264 Video Codec provided by Cisco Systems, Inc." (See screenshot). Why doesn't it get installed? And do I need this add-on or is it unnecessary anyway?

Regards, Adrian

Hello, any luck if you toggle (double-click on it) the media.peerconnection.video.h264 to True in about:config ? After that exit firefox and restart it.


thank you
