What really happened with both of my computers and the new Firefox 3.6 is not the result of any interaction between the Java program and Firefox.
In fact, it was an add-on that was causing incompatibilities with Firefox.
Firefox is so widely admired because it can be customized with helpful add-ons to improve your browsing experience. However, occasionally these add-ons need to be updated or removed.
You can view your Firefox add-ons by going to the tools menu, Add-ons, and then clicking Extensions. It’s generally not good to touch the Java add-ons or the Microsoft .NET add-on. Others you may or may not need; they may even be obsolete.
