Need some CSS help with my theme

I’m actually using Chrome, should I switch to FF?

This is what I’m using to try to change the font:

/* fonts
————————————————–*/

@font-face {
font-family: ‘Libre Baskerville’;
font-style: normal;
font-weight: 400;
src: local(‘Libre Baskerville’), local(‘LibreBaskerville-Regular’), url(http://themes.googleusercontent.com/static/fonts/librebaskerville/v1/pR0sBQVcY0JZc_ciXjFsK5Rby8KfwQsaipLBqMCVNtM.woff) format(‘woff’);
}
@font-face {
font-family: ‘Libre Baskerville’;
font-style: normal;
font-weight: 700;
src: local(‘Libre Baskerville Bold’), local(‘LibreBaskerville-Bold’), url(http://themes.googleusercontent.com/static/fonts/librebaskerville/v1/kH7K4InNTm7mmOXXjrA5vz8SLKRGgamuUl1hIefMyNI.woff) format(‘woff’);
}
@font-face {
font-family: ‘Libre Baskerville’;
font-style: italic;
font-weight: 400;
src: local(‘Libre Baskerville Italic’), local(‘LibreBaskerville-Italic’), url(http://themes.googleusercontent.com/static/fonts/librebaskerville/v1/QHIOz1iKF3bIEzRdDFaf5dgliI79_bmRXH6crmREtCo.woff) format(‘woff’);
}
