I downgraded Firefox to 23, then 20. I still doesn't work. I know it did work in Firefox, and now it doesn't, but the problem must not have been caused by the Firefox upgrade.

The menu works fine in other browsers.

Can you think of anything that would cause it not to work in Firefox?

Thanks.

solved.

I had to add the following to mootools

String.prototype.contains = function(string, separator){

return (separator) ? (separator + this + separator).indexOf(separator + string + separator) > -1 : String(this).indexOf(string) > -1;

};

of course.  ;)
