Status: RESOLVED DUPLICATE of bug 784131

Description

[Alice0775 White]

Audio does not stop after close a video.
This problem happens since Firefox13. And persists in Firefox14.0.1, 15.0 and 16.0Beta.
Unfortunately this issue is unable to reproduce. Because, Flash player fails to load in Aurora17.0a2 and Nightly18.0a1.

Closing tab helps.

Steps to reproduce:
1. Open http://edition.cnn.com/2012/06/25/health/georgia-flesh-eating-bacteria/index.html
2. Scroll to down
3. Click "Click to play" of thumbnails
4. Wait to start the video
5. Click "CLOSE X" button at the top-right cornar of the video

Actual results:
 Audio does not stop.

Expected results:
 Audio should stop.

I think it's a dupe of bug 784131.

Thanks for the test case here, this is in fact a duplicate of bug 784131, and I think I know the cause
