What can I do about this: After upgrading to firefox 6, I get this error. When I click to open Firefox, A box open with the following error: JAVASCRIPT Application TypeError: Components.classes[cid] is undefined? After I click close on the box, then Firefox will start. I really just want to get the error fixed so that when I want firefox open, I don't have to see this box anymore.

You need to figure out which add-on is causing that error and disable it until the developer of that add-on fixes it. There may be an error message about that in the Error Console, accessed through the Web Developer menu item or through {Ctrl + Shft + J}.

I appreciate your help. I found that my Java console was the error and I have updated it and the problem has been solved.

Thanks again for your help in this matter.
