When I log into my forum with different web browsers the font is different for the top navigation bar

In Safari everything looks as it is intended
In Chrome the navigation bar looks bolded (don't like that either)
but in Firefox it is completely the wrong font.

Here is a video demonstrating the issue : https://youtu.be/ZsqhIYulFIw

I uploaded the fonts into my forum directory and I changed the CSS in my theme to this :

@font-face{
font-family:'BebasNeue';
font-style: normal;
font-weight: normal;
src:url('fonts/BebasNeueBook.eot') 
format('embedded-opentype');
src:url('fonts/BebasNeueBook.ttf')
format('truetype');
src:url('font/BebasNeueBook.woff')
format('woff');
src:url('fonts/BebasNeueBook.otf')
format('opentype');
}


	#nav {
	font-family:'BebasNeue',sans-serif;
	width: 100%;
	float: left;
	margin: 0 0 0 0;
	padding: 0;
	background-color: #343236;
	height:95px;
	vertical-align:middle;
	position: fixed;
	z-index:999;

Thanks in advance for the help
