Looks like a wrong media query ? You have the same appearence in Firefox that you have in Chrome if you resize the browser window to a small size ?
Else using F12 I sometimes disable styles on the offending element (or surrounding element until it shows as expected) and put them back one by one to find out which one is causing the issue (what if you start by not forcing the width for your navbar-brand
Edit: usually in F11 you have a checkbox next to styles which make easy to disable/enable styles to experiment a bit with your design...
