Stop auto play HTML5 in Safari?
With the upgrade from El Capitan to Sierra, ClicktoPlugin is very much broken. So now videos on sites such as YouTube, CNN, and others are all auto-playing again.
I've read that Sierra has a feature to stop this from happening - it involves going to Safari Preferences:
Go to the Security tab, then Internet Plug-ins. Allow Plug-ins should be checked, then click the Plug-in Settings button.
Then choose QuickTime, set "When visiting other websites" to Ask. HTML5 should then stop auto playing video.
The problem is this doesn't work, as there isn't any QuickTime plugin listed.
So does anyone know how to stop HTML5 from playing in Safari 10, under Sierra?
