I recently started receiving the following console errors, without any code changes taking place.
I did not install any extensions recently.
Failed to load resource: net::ERR_FAILED chrome-extension://enhhojjnijigcajfphajepfemndkmdlo/cast_sender.js

I have several YouTube player embeds on the page that are triggering this error, but they are simple:
<iframe width="100%" height="100%" src="http://www.youtube.com/embed/OUR_YOUTUBE_ID?showinfo=0&wmode=transparent" frameborder="0" allowfullscreen=""></iframe>
Has anybody else experienced this?
