What website? What type of applet? Are all your plugins up to date (Flash, Java, etc.)? Does the issue still occur if you start Firefox in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode How about with a new, empty profile? http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile

I guess that this is a dupe of bug 718939 Reporter: Please add more information in a bug report. Providing an example URL is always a good idea. Please reopen this bug if this report is not about java applets.
