Facebook video calling problem in Safari I have a little issue with Safari. I can't make video calls with Facebook Messenger in Safari. I know that with Google Chrome or Firefox we can avoid this problem, but as you know Safari is optimized for macOS.

I've tried to use a user's agent but it doesn't work. Is there a way to use the Facebook video calling feature with Safari?
Facebook video calling is not supported on Safari (and hasn't been for years).

Apple hasn't indicated they will support this nor has Facebook indicated they would change their code to accommodate Safari.  

Your options are to provide feedback to Apple or Facebook, telling them you'd like this feature supported.
