After changing its stable release policy to a more accelerated pace, Mozilla released Firefox 5 pretty quick after the latest major Firefox version was put out. Firefox 4 was released on March 22, 2011 and this version follows only three months later. Here’s an announcement on the Mozilla Blog website.

Microsoft's Internet Explorer (IE) browser lost nearly a percentage point in market share in March, according to the latest statistics from Web analytics firm Net Applications.

The browser war between Microsoft and Mozilla came to an end in 2001 when Microsoft released Internet Explorer 6. Now it appears that the browser war is back, but this time it is different. There are five major browsers.

Gone are the days when Microsoft's Internet Explorer was the sole rival for Mozilla's Firefox. A new open-source browser, Google Chrome, has come to town, and it's from the company that provided $66 million of the Mozilla Foundation's $75 million in 2007 revenue.

From the 'What Happened to Firefox 3.6.1?' files: No, that's not a typo. Mozilla is currently scheduled to release its next open source Firefox browser version 3.6.2 on March 30th.

Mozilla Firefox has been outperforming Internet Explorer for a number of years, and its latest version is even faster than ever. However, there is a new, lean, free web browser on the block which runs web pages at lightning speed. It goes by the name of Google Chrome. Google released the source code of Chrome, including its custom JavaScript engine as an open source project entitled Chromium.

Though the" [Free Software] "web browser continues to sit firmly in second place behind IE, where it's been for years, usage of Firefox is still on the rise. The browser is even threatening to tip the scales in some European countries -- most likely thanks to the rapid internationalization efforts made possible by the open-source development model..."
