Firefox 3 + Flash Player 8.0 on up bug (button action

The embedded video player I set up for my employer relies heavily on javascript
for swfobject / embed and many controls, along with communication between the
player and our backend. The QA department has found that the player's controls
will not function with the new build of Firefox (3.0 soon to be released). We
support player 8.0 on up and all of these versions will not function within
Firefox 3.0. Currently, though all browsers and versions DO function. The
button action themselves are your most basic action (i.e. myMC.onPress). We
also have other flash elements on the page that do work in Firefox 3.0 however
these do not rely on javascript.

Any suggestions or anyone else having similar problems? I checked the Mozilla
bug checker and didn't really see anything similar.

Thanks!
