I get a warning box on startup with text: "TypeError: Component.classes[CID] is undefined" After clicking ok, FF starts up. This happens after a restall. 

Reproducible: Always

Steps to Reproduce:
1. uninstall Microsoft Visual C++ 6.0
2. startup Firefox

I have uninstalled Microsoft Visual C++ 6.0

Not quite clear what MSVC has to do with this.  Please explain more.

Regardless, I suggest giving Firefox safe mode a try:
or possibly a new profile:

It sounds like an add-on of some sort is doing this.  If it doesn't have this error in safe mode then that's probably the case.  Disable the add-ons one at a time until you find the cause.  (try plugins after extensions if you need to)  If you find an add-on that does this, then please reply back here with its name and version.

You are quite right. I should have tried that from the start. It tourned out that it was the AVG Safe Search 8.0 that was the culpit.

Thank you. :)

Glad to hear you've solved the problem.  FIXED is for when a bug has been fixed by a change from Mozilla.  This bug is INVALID because it turned out to be an AVG problem.  Please report this issue to them.
