Hi,

First of all, Your website looks the same on Firefox and Safari on Mac as well as Chrome on Windows, there is no vertical black line and the right arrow is a bit nearer to the edge. Please see screenshots.

Safari on Mac http://prntscr.com/7stzw1
Chrome on Windows http://prntscr.com/7su7hd

There is no class name to target specific browser, Using my Firefox browser and firebug extension, I can only provide you custom css to balance the arrow positions.
Please use the following in Theme Options -> Custom CSS

That’s all I can help on this issue.

You may want to try out other sliders, such as revolution slider and layerslider that comes with the theme.
You are using a very old version of Evolve Plus theme, you can download the latest theme version 1.9.0 from your admin account on this website.

Thanks!
Denzel
