I recently moved my website onto a new web server, and all of a sudden, attempting to load any of my applets in Firefox 3 for Mac crashes it.  These applets work perfectly in Safari and other browsers.

Maybe something changed recently in Firefox (I updated to 3.0.11) or Java (via OS X Software Update)?  Or could my recent web server move have to do with it?

Here are two examples of applets that crash Firefox, but work in other browsers:

A signed applet that uses OpenGL:
http://alignedleft.com/projects/2009/ColorMapper/applet/

An unsigned, simple applet that uses regular P2D:
http://alignedleft.com/projects/2008/Anticipation_Study_1/applet/

I just checked the Console, and there are a ton of error messages generated by Firefox during the crash.  Two that seem relevant are pasted below.  Any thoughts?

The problem isn't on the server, it is on the client side. Looks like an update of Java (at least the version used by Firefox) removed some Sun proprietary API...

Super, thanks.  Glad it works for you on Windows.

I also found this thread:

Looks like maybe this is a just a Java issue, and all I can do (besides reverting back to prior versions -- major headache) is wait for an update.
