Mozilla on Tuesday pushed out a new version of its popular Firefox web browser for Windows and Mac computers. Mozilla released Firefox 6 on August 16th, just over one month ago, and version 7 is already upon us, reaffirming Mozilla’s commitment to the world’s second most popular web browser. Firefox 7 brings with it a host of changes, the most notable of which is perhaps “drastically improved memory handling” and other speed related improvements. As of August, Net Applications shows Firefox’s global browser share as 22.57%, behind Microsoft’s Internet Explorer (55.31%) and ahead of Chrome (15.51%) Safari (4.64%) and the Opera browser (1.68%). Firefox 7 is available for download immediately from Mozilla’s website, which is linked below.
