I'm hesitant to think we should go this far. A reasonable start
would be to list the formats that the browser has built in. Listing
plugins here might clutter it up, especially as more are added, so it
might make sense to separate them off somehow. And if we put the
plugins in a separate list, how sensible would it be to have all
installed plugins in one list?
