Slider not working in Firefox

It's working fine in Chrome, Opera and Edge but not Firefox. See  www.itsbespoke.com/

Any advice would be appreciated, thanks.

Hi
I have exactly the same behavior on Chrome, Firefox and Edge
an image is displayed, but it never changes

Please try with a new Slider CK module and the default data, tell me if it works
Not sure if there is a problem in the settings, or in the page

Thanks Ced. I'm away from my laptop until the weekend so I'll get back to you as soon as I can try a default module.

ok let me know

Hi Ced
So I've added a new default module as you can see in the attached image. It behaves just as the other SliderCK module - works fine in Chrome, Edge and Opera but not Firefox.

I've unpublished the module now as this is my clients live site.

Edit: I cannot add a screenshot as your allowed Maximum File Size of 0.1mb is too small.

Please clear your browser cache
by my side it wors now on both browsers ... may be that you had cache on your website ?
please check and tell me
