Mozilla has just released a new milestone version for their recuperating web browser. Firefox 20.0 offers -- as with most new versions -- a combination of stability improvements, bug fixes and HTML5 additions so you can browse the web with less hiccups. Although that sounds far from interesting, this latest stable release also introduces a few new features that are worth highlighting. Among them are an improved private browsing mode, a new download experience and the ability to close hanging plugins without the browser itself hanging.
