863350 - Websites can mute flash videos in other tabs

Status: RESOLVED INVALID

(Core Graveyard :: Plug-ins, defect)

Description

I was listening to a music video in YouTube while reading an article and I wanted to translate a word in a website called "Morfix". I found out that whenever I press the pronunciation button in that specific website it causes all flash videos (even in other tabs) to mute. The bug doesn't occur in Google Chrome and in IE.

To reproduce the bug, enter a website with a flash player (such as http://edition.cnn.com/video/#/video/tech/2009/08/26/dcl.data.doc.firefox.cnn?iref=videosearch ) and the Morfix website (e.g. http://www.morfix.co.il/en/ecclesiastical ). Play the video in the first website (make sure it makes a sound), switch to the Morfix website tab and press the button with a silhouette of a speaker (placed right beneath the English word).

Can you please try to reproduce this issue in safe mode or with a clean profile?

Please notice that I'm using the beta version 21.0.

All the sound handling is done in Flash here, so this is not a Firefox issue.
Please report this with Adobe.

No, because the issue only happens when I use Firefox. In Google Chrome and IE it works flawlessly. I suppose the bug lies somewhere in the integration of Flash in Firefox.

Both Chrome and IE use different versions of Flash.
The behaviour in Opera is the same as in Firefox.
