WGTadmin2:
I can just suggest that you update to the 11.4 non-pepper version of flash
WARNING!
Freeze problems with Firefox and Flash 11.4 made me return to Flash 10.3 - downloaded from adobe.com. I reported in your "Flash 11.4 rolled out - need help" thread. I suspect that you read (and ignored?) it like your board and customer service team has been reading / ignoring this thread for almost six weeks now.
OTOH, Pepperflash is typical to Chrome. There's apparently no Pepperflash available in conjunction with Firefox.
