Safari

Since august 2017 Safari 11 introduced a feature to enable autoplay video per site. However, default auto-play is disabled for all sites.


  1. You can change how video should behave. Click on Safari > Settings for This Website or right-click the URL box and select Settings for This Website.



2. A pop-up will appear underneath the URL box. There is a listing that says Auto-Play. If you move your cursor over the phrase next to Auto-Play, you will see that it turns into a pop-up menu with three choices:


  • Allow All Auto-Play
  • Stop Media with Sound
  • Never Auto-Play


3. Now click anywhere on the screen to make the pop-up disappear.


You can always go back to this Safari preference if you want to change a setting for a website.


Chrome

Recent Chrome updated the play behavior. They have disabled previous existing flags. However there is still a way automatically activate autoplay via site settings


  1. Settings
  2. Advanced
  3. Privacy and Security
  4. Site Settings
  5. Sound

Use Add to allow one or more sites.
