First, I'm no expert. Just waiting for an answer for my own problem/question.

Anyway, that red circle with white X in it gives me the idea that maybe some security program is blocking it. Maybe think about what kind of security is running, and look at them?

Or even look at Firefox settings > Privacy and Security? Possibly your other browsers are using different security settings?

Well, some things to look at until the experts come along.

Good luck!
