I am expirencing a very strang issue. All (or almost all) youtube videos embeded using IFRAME (much like on this page) show themselves as black boxes in my Firefox. All other videos (like the first you on said page) show themselves normally, and I also can watch any of the videos from black boxes on youtube, if I figure out the path.
I use folowing script (run in youtube iframe) to try to find the video:

  1. How do I fix my firefox?
  2. Is there a better way to find out path to embeded video?

Does the same page look ok on other browsers? Have you tried uninstalling and reinstalling Flash? (Follow the steps mentioned here). – Karan Feb 17 '13 at 23:45
I tried to reinstal flash. – Tomáš Zato Feb 18 '13 at 0:00

What solved this issue for me was the following:

1.Go to you tube, click on share, then on embed and copy the <iframe> code into your source code in the editor you are using to upload posts.

2.Your code will look something like this:

iframe width="420" height="315" src="//" 

  frameborder="0" allowfullscreen></iframe

(i had to remove the tags, because it wouldn't show up my comment)

3.Now, at the end of the URL, which is this part: src="//" add ?rel=0 So it will look like this:



This might solve the issue.

I might be able to give you an answer to your second question. Click the share button under the video; then click the second tab out of the row. It bwill give you a frame to embed your video.

My friend, do you see the screenshot? Well, if you do, I'm really sure you do NOT see any button. That is the problem. Flash does not load at all. – Tomáš Zato Feb 17 '13 at 22:24
