firefox 4 beta 6 crashing java?

Okay, so a good friend of mine tried my beat em up applet in Firefox 4 b6 and it crashed for him over and over.
I tried it in 4b6 and it crashed the first time and worked normally after that.

I’m worried bout Firefox crashing other java apps, and making java look bad.

Has anyone ran java nicely on Firefox 4b6?

isn’t firefox suppose to have a out of process plugin thing thats stops a plugin from ever crashing the browser?

sounds like a ff bug.

Isn’t 4 a beta? So probably bugs that should be reported…
Is it crashing your app or Java VM itself?

Does your friend use AdBlock Plus?
