Website is missing Plugin features in some browsers

I am using the Hueman theme for my website. The way I set up my website in my dashboard with some plugin features shows up well when using Google Chrome. However, when using Safari and Firefox browsers, my website is missing information. For example, I installed and activated the plugins Metaslider, Twine Social, and Social Warfare and all those features are missing from my website when viewed in those browsers. However, when viewed in Chrome, the features show up.
