Firefox Query

FIREFOX QUERY….I have a Firefox question. Frequently, when I click a hyperlink, the page jumps slightly and my mouse is no longer over the link by the time I release the mouse button. When this happens, I have to move my mouse and click the link again.

Needless to say, this is annoying. In fact, it’s the only real complaint I have about Firefox. Does anyone have any idea what might be causing this and how I can get it to stop?
