So since this is evidently going to be baked into the browser, what security measures will be put in place to prevent some nefarious coding from turning on my laptop's webcam as soon as I visit a bogus site?

This is not meant to disparage Mozilla, it's honestly the first thing that came to mind when I read the article.

EDIT: Why not answer my question instead of simply downvoting me? This is an honest question, coming from a vocal Mozilla supporter.
