Unsafe JacaScript attempt to access from with URL http://localhost:3000/resumes/1 from frame with URL http://player.vimeo.com/video/61229815. Domains, protocols and ports must match.
Also, the maxWidth method isn't working and sometimes it shows duplicates of the embeded video.
A: This is a bug in webkit which is used by Chrome and Safari. Basically the Vimeo is trying to access the parent window which is on a different domain. The same thing happens with you Youtube embeds, you can safely ignore this.
The embedly-jquery lib doesn't de-dupe links, you would need to narrow your CSS selector to handle that.
