I have a slider that I have been using for a long time without problems, however, I have now discovered that in FireFox from I think version 25 onwards sometimes the slider runs properly on page load and other times it doesn't, if it works and I refresh the page with the refresh icon it may or not work, if I go into the address bar and press return it works.
It works fine on IE, Chrome, Safari and Opera, I have uploaded it to the site below if anyone can help;
Thanks
