Optional permissions are used so you can control what gets paused.

Security:
The extension may ask for access to websites that you add to its options page.
This is so the extension can receive media events like "play" "pause" and so it can control the media playbackRate it will also use the audible property of the tab which does not require any permission.

On websites that it has permission for where media elements are not added to the pages DOM the extension will insert a local script in the pages context to add it automatically.

Fingerprinting:
The use of this extension maybe detected by the website you use such as if the media gets paused on window.open
