Option to disable/enable autoplay, disable autoplay by default

[BlobCodes]

Is your feature request related to a problem? Please describe. Most browsers prevent websites from autoplaying media and sound automatically, by default. When I, for example, open multiple youtube-videos in different tabs, I think it is very disturbing to see this non-standard behavour.

Describe the solution you'd like By default, all media is prevented from playing automatically. Via the settings, one is able to change the default behaviour. Also, an option to change the behaviour per-site would be very nice.

Describe alternatives you've considered None.

Additional context None.
