Since it is a 64/32 bit browser issue, this is related:
The 64 bit version of Firefox is called Waterfox. It is NOT written by the same group of developers, but uses the same core and is also free.
I've mentioned it here before and a few have tried it.

/Kinda like BiaB in that Firefox works fine at 32 bit.


Make your sound your own!
