(FireFox) ReferenceError: tipOver is not defined

I get this error:

ReferenceError: tipOver is not defined - jquery.tipsy.js: 26

... in FireFox js console (not IE, Chrome or Safari). This can be fixed by moving $tip... after the functions declarations:

                //Patch to hover over the tooltip
                var that = this;
//		Remove this line from here:
// 	        $tip.hover(tipOver, tipOut);

                function tipOver() {
                    that.hoverState = 'in';
                }
                function tipOut() {
                    that.$element.trigger("mouseleave.tipsy");
                }

//		Place here:
                $tip.hover(tipOver, tipOut);

... also the developers version (without above 'patch') at http://onehackoranother.com/projects/jquery/tipsy/javascripts/jquery.tip... also works without breaking FireFox's js console.
