There are elements that look different from how they are supposed to look on Firefox but, everywhere else, it looks fine.
This is how it's supposed to look (Chrome):

This is how it looks on Firefox:

On Firefox for the width of the image to be how I want it I have to set the width of the image to 200% instead of 40%. I tried looking for specific -moz- commands but they don't work. I would like the Firefox version to be the same as the Chrome version. How do I go about fixing this.
Thanks in advance for the help.

<div class="about-container appear appear-hidden" id="about-scroll">
<h1><span>About Me</span></h1>
<div class="about-children-container">
<div class="about-p-container">
