Doesn't really work anymore =/

Can't seem to make it show permissions for an embedded cross-origin iFrame. It only seems to show permissions for the top level document. I need to check the iFrame's permission, can you support something like the console does, where you can choose the context from a list?

Doesn't seem to work on LinkedIn.com. I click on autoplay to make it 'none', but the videos on LinkedIn's feed still play. Am I missing something?
