[JavaScript Application] Type Error: Components.classes [cid] is undefined. How do I get rid of this message it shows up with some, but not all web links. Thanks for your help.
I am on a MacBook using Mac OS10.6.6. I reinstalled the most recent version of Java for Macs. The message is more annoying (I have to make it go away to finish what I was doing) than disruptive. However, it happens frequently if I am browsing. Thanks for your help.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
- Don't make any changes on the Safe mode start window.
See:
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
- Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
- Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
- Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
