Ubuntu Linux - Having an issue?

Hello! I am just starting school this fall and my laptop needs to have linux on it. I want to play roll20 games when I'm not near my other computers. Every time I try to join one of my games, I keep getting this error: "Script: <a href="https://app.roll20.net/js/jquery.1.8.2.min.js:2" rel="nofollow">https://app.roll20.net/js/jquery.1.8.2.min.js:2</a>" does anyone know how I could fix it?

Hi, Netzah . What happens when you visit this diagnostic webpage? <a href="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js" rel="nofollow">https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js</a> The page should display "/*! jQuery v1.8.2 jquery.com | jquery.org/license */" followed by a bunch of code if all is well.
