Since I installed 4.0, every time I try to go on the internet, these appear: "TypeError: Components.classes['@softage.ru/skype/SkypeFfExtension;1'] is undefined TypeError: Components.classes[cid] is undefined" . Why and how do I make it go away?

Every time I open firefox 4.0, it says, TypeError: Components.classes['@softage.ru/skype/SkypeFfExtension;1'] is undefined TypeError: Components.classes[cid] is undefined

Is this a Java Application error? A Skype error? or something else?

When I go to extensions, it says I have none.
