Mozilla has published Firefox 19, with one of the most interesting new features being a built-in PDF viewer. The new feature uses PDF.js, a JavaScript library that converts PDF documents into HTML5. Other than that, the update promises faster startup performance, new HTML5 CSS features and some bug fixes. If you're running Firefox your browser will automatically update, otherwise you can download the new build over here.
