Social Icons not rendering in firefox

Some of the social icons are not being rendered in firefox v 56.0 (32bit). To name few social-linkedin, social-twitter are not being rendered even in official website.

@bhubanstha - Do you have any extensions that could be preventing social media information (links, icons, etc.) from loading?

For example, I use Ad Block Plus. If enabled, the Simple Line Icons preview page won't render a handful of the social media icons. In my case, opening Developer Tools reveals that some of the social media icon selectors have the display: none !important; declaration, because of an injected stylesheet courtesy of Ad Block Plus.
