When using the Java Platform SE 6u10 plug-in with Firefox, the VM throws an exception. The Java console shows an exception similar to the following:

Although the page content loads and interaction with the page is possible, the status bar indicates that the browser is waiting for the collection server to respond and it continues to display a busy/loading status. Upon closing the browser tab after seeing this behavior, Firefox fails.
Upgrading to later builds of the Java VM correct the problem.
