Description

[Michael Merrell]

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)
Build Identifier: 3.0.11

There are several Java Applets that I have identified that cause Firefox 3.0.11 to lock and not allow the user to do anything at all except force the browser shut.

The easiest way I have found to reproduce this error is to go to Java.com and then click on the "Do i have java?" button which seems to cause the browser to lockup.  

Reproducible: Always

Steps to Reproduce:
1. Open up Firefox 3.0.11
2. Go to Java.com
3. Click on the 'Do I have Java?' link.
Actual Results:  
The windows hourglass icon came up and the browser was unresponsive to any commands.

Expected Results:  
The Java applet should have loaded and detcted which version of Java I was using.

I have tried disabling all add-ons/themes and this still occurs for me.
I have Java 6 Update 14
