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.

The extension should never make any external requests or ask for permissions other then what the user requested. If any security issues are found please email me using the support email and report to Mozilla if required.

Fingerprinting
The use of this extension maybe detected by the website you use such as if the media gets paused on window.open or a script gets added to the page context.
