When i play movie in youtube or metacafe (maybe in more sites) it plays movie without sound. (after i promate in noscript)

Reproducible: Always

Steps to Reproduce:
1. Entering youtube/metacafe/other site
2. promate j.s running in noscript
3. page refresh
4. movie plays but sound not, even when i turn volume up.
Actual Results:  
the movie plays without sound (i open ie :( )

Expected Results:  
play movie with music.

i think its releted to my other bug (Bug 410805) - https://bugzilla.mozilla.org/show_bug.cgi?id=410805
its all began when firefox updated from 2.0.0.10 to 2.0.0.11 (and not really updated)
i'm using adblock, noscript safecatch, safehistory, trackmenot and dom inspector.

tried to fix this problem in safe mode and with new profile.
this is my second bug i report (and maybe will be another one), so please relate this like as a normal bug.

thanks.

Please try Firefox's safe mode since you are using extensions. http://support.mozilla.com/kb/Safe+Mode

The sound is directly played by flash, are you sure your windows default sound settings are correct ?

don't understand your question...

this is the situation:
i can listen to music for example.. with winamp...
i can listen to music from IE!
but i can't listen to music in firefox... and i think its totally because of firefox cause i tried yesterday to listen music in another site and wasn't heared any music... it could be corrupt or something i don't know... but what i'm do knowing for sure is that every thing with firefox settings (cause i tried it with a new profile) and it worked on ie and sound settings are on cause i can play music in winamp.

Again, Firefox doesn't play the sound, the flash plugin plays sound.
It's clear that nothing in the firefox settings can cause this because it's the flash plugin which plays the video and also the sound for youtube.
"i can listen to music from IE!" means nothing because Ie is using an ActiveX flash plugin while all other browsers are using an npapi plugin.

You can see the used plugin in "about:plugins" and a version of the plugin should be always included in a bug report if you have a problem with a plugin.
But in this case i would try to just look at the windows settings for your sounddevice (maybe you changed your sounddevice recently) and also install the latest flash plugin from adobe.

and whene is red box in allowed filed, it means "no", the rest of the parameters is "yes".

about the plugin - i installed the latest version.
about my sound device, no changes made recently (if at all).
so for no change.......
