teste dos links java

Ola galera, é o seguinte, tenho um site que é todo programado em php e java mas alguns recursos pararam de funcionar possivelmente foi os links de bibliotecas externos que não existem mais, alguns ja consegui identificar, mas tenho que abrir o código e testar link por link, eu sei que no firefox faz isso, mas não consigo me lembrar como. Alguém pode me ajudar ae?

Exemplo:

</script>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script>

<!-- The jQuery UI widget factory, can be omitted if jQuery UI is already included --> <script src="js/vendor/jquery.ui.widget.js"></script> <!-- The Templates plugin is included to render the upload/download listings --> <script src="http://blueimp.github.com/JavaScript-Templates/tmpl.min.js"></script> <!-- The Load Image plugin is included for the preview images and image resizing functionality --> <script src="http://blueimp.github.com/JavaScript-Load-Image/load-image.min.js"></script> <!-- The Canvas to Blob plugin is included for image resizing functionality --> <script src="http://blueimp.github.com/JavaScript-Canvas-to-Blob/canvas-to-blob.min.js"></script> <!-- Bootstrap JS and Bootstrap Image Gallery are not required, but included for the demo -->

<script src="http://blueimp.github.com/cdn/js/bootstrap.min.js"></script>
<script src="http://blueimp.github.com/Bootstrap-Image-Gallery/js/bootstrap-image-gallery.min.js"></script>

<!-- The Iframe Transport is required for browsers without support for XHR file uploads --> <script src="js/jquery.iframe-transport.js"></script> <!-- The basic File Upload plugin --> <script src="js/jquery.fileupload.js"></script>

Como saber se todos os links estão funcionando pelo navegador
