It appears that Firefox is keeping up with its plans to roll out quick release versions of its Firefox Internet browser. With Firefox 13 being made available a little before its officially launched. New changes within the latest Firefox 13 release include a new most visited page feature, that is now shown when you open a new tab.
Together with the default Firefox browser home page now enabled with quicker access to bookmarks, browsing history, and Firefox settings, to name just a few enhancements.
Other new features include SPDY protocol enabled by default for faster browsing on supported sites, and smoother scrolling. For more information jump over to the FireFox website for more details. If the link to the download has been removed, don’t worry the full Firefox 13 version is releasing very soon.
