I've upgraded to FireFox 4 recently and suddenly one of my flash modules stopped working. This a copy/paste of the object structure from firebug (double dots are there for simplicity):
<object width="100%" height="100%" type="application/x-shockwave-flash" data=".." name="..">
<param name="flashvars" value="..">
<param name="wmode" value="obaque">
<param name="allowscriptaccess" value="always">
</object>
Now... what's that obaque value on wmode param?.. It was meant to be "transparent" actually, at least that's what I had in my embed code.
Looks like it is the bug caused by FlashFireBug.
in Apr 18, 2011 by Ashraf Amayreh Fixed the obaque problem, waiting or Mozilla's approval.
in Apr 14, 2011 by Guest I discovered a problem with the param wmode=transparent for a flash object on Ubuntu 10.10, FF 3.6.16. Window mode is reset to "Obaque" (which should be "opaque" I think) with activated FlashFirebug. Thank you so much!
