Computerworld - There has been a lot of buzz in the past few months over the arrival of Firefox, the open-source browser published by The Mozilla Foundation, and how Microsoft's Internet Explorer is starting to lose some of its share of the browser market to this new competitor. Out of the ashes of Netscape, Mozilla has built a solid browser that supports features such as tabbed views, Google for native searches and direct support for RSS feeds.

Many mission-critical applications have been built on Internet Explorer, and most organizations don't have the budget or resources to recode them. In addition, PCs' application loads need to be properly tested to ensure that nothing breaks with the addition of a different browser. In the near term, many business users will be better served by keeping Internet Explorer and installing security updates as they're released. If they aren't dependent on Internet Explorer technology, however, some end users could use Firefox for their daily Web surfing while reserving Internet Explorer use for sites that require it.
Despite the factors that should keep many business users from adopting Firefox at the expense of Internet Explorer, I believe this new browser is going to
