Everytime I visit flash based webpages with audio content I wonder why there is no mute button in the right-click options of a flash file?. Why you may ask – I am listening to music in Windows Media Player like I am now and so I don’t want to mute my entire machine; I keep browsing and to my annoyance a webpage starts playing loud audio and I can’t mute that webpage alone.
Since I haven’t heard any one else raising this, I kept saying to myself I should be crazy. Thank God, I am not alone (or crazy) – I recently came across this same ask in an Adobe Employee’s blog, scroll down to the third comment section.
Adobe doesn’t seem to be listening (may be they have muted themself out to user comments 
) as I don’t see this feature even in their new Adobe Flash Player “9″ version released several months after this post.
