Analyst firm Gartner has said that companies should think carefully before migrating from the Internet Explorer browser to the open-source Firefox browser from Mozilla.
The Gartner report said Firefox’s growth, so far, was "unsustainable" as many of the features that had made it popular were primarily aimed at individual users not businesses.
In the US, Firefox now has 5% of the market and is still rising, while Explorer’s share is slipping.
New features in the latest Firefox browser include easy installation and removal, tabbed browsing and integrated search.
Gartner analyst, Ray Valdes, said Microsoft may consider hitting back against Firefox with an upgrade, but this would depend on its Windows upgrade plans and the development of the impending Longhorn operating system, the next major upgrade of Windows.
Gartner said the most likely scenario in the future is that Explorer will co-exist with Firefox on PCs as companies install Firefox as a back-up browser and to make sure they do not miss out on future features.
Another probable factor in Firefox failing to severely dent Explorer’s base in the commercial sector is the increasing number of worms and viruses now targeting Firefox and other browser alternatives to Explorer.
