Different forms of website in browsers

Different forms of website in Mozilla Firefox and Google Chrome.
At first, they have different fonts.
Secondly, as you can see, there aren't icons under "You can contact me via:" in some case.

This form has your web site http://yulijia.net/freshman21 in Google Chrome:

I tried to open another website with your theme. And there are such differences too.

Sorry to have bothered you, I solved my problem with icons under "You can contact me via:" by adding the line in file _includes/head.html:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">

@RAlexeev css file is ./freshman21/css/main.scss

@import url('https://maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css');

you could change it to 4.7.0
