Homepage Box Slider (FIX) for the Firefox browser.

Note: the non-selectable slider is not an FSB error.
It is a Firefox error that came up with v.59.

Again-Note. No matter which version of FSB is running your site, the slider will not work in FF v.59 because it is a problem in the FF browser.

Below is a temporary patch that will solve this problem. Simply place it in the section of your footer in parameters and save it. Remove cache if you do not see immediate results.

Cheers!
