Firefox and Adding Youtube Video

It was recently discovered that Firefox users with version 3.6.9 or 3.6.10 are not able to add Youtube video using the "Embed Media" tool found on the content editor menu. This is due to a confirmed bug introduced by Mozilla with a security change to Firefox. According to the support ticket submitted to CKEditor the next Firefox update should address this issue. You can view the ticket at http://dev.ckeditor.com/ticket/6275. In the meantime Firefox versions prior to 3.6.9 as well as Internet Explorer do not have any issues with adding YouTube video embed code.
