Problem with IE-FF-Opera/Facebook?

Hello

At home, I have no problem on FB, with IE, FF, or Opera.

But at work, with the 3 navigators, I can't click on button.

Exemple, the button "more" to see the applications.

I can view messages but can't replay, the button "send" doesn't work.

And with some applications, the "next", "buy" or others buttons doesn't work too.

The error ont he page at arriving :
