While Firefox has made an impressive start -- reaching more than 10 percent market share and dropping IE to around 84 percent, according to the latest numbers from research firm Janco Associates -- it is a long way from usurping Microsoft in the new-millennium equivalent of the '90s browser wars.
"There is a chicken and egg effect whereby Firefox won't be completely successful until it gains broad support from enterprise applications/solution providers, yet it won't obtain that support until it reaches at least a 20 percent share," says Jon Collins, an analyst with UK-based IT consultancy Quocirca Ltd. "In my opinion, Microsoft will make sure that it doesn't lose this war."
Firefox certainly has plenty of advantages over its Redmond rival. According to Gartner Inc. research director Ray Valdes, it is more nimble than IE because it is separated from the operating system. Other advantages, he says, include tabbed browsing and an integrated search engine that save time and system resources.
"As well as tabbing and Google-search features, Firefox is small enough that it can be installed and deinstalled easily," says Valdes. "However, it is primarily oriented to individual usage, not the enterprise."
And there's the rub. While many use it personally and love it, they can't always utilize it at the office. In many cases, financial applications and corporate intranets are actually integrated with IE and are coded to depend upon IE's features.
"I'm a considerable Firefox fan myself due to its more functional interface, but some web sites just don't work with it," says Gordon Haff, an analyst with Illuminata Inc. of Nashua, N.H. "Firefox doesn't support ActiveX controls, for example, and it definitely doesn't work with Microsoft Windows Update."
This isn't because Firefox is broken. It's due to some web sites being architected in IE-specific ways that cause them not to operate properly with Firefox. This fact could prove to be a barrier to enterprise adoption. IT help desks may find it easier to stick to IE rather than be subjected to a stream of calls about web pages not displaying or working properly on Firefox.
Collins, though, doesn't believe this to be a significant problem, based on his own experience.
"On the whole, Firefox is better than most at presenting sites that have been optimized for IE," he says. There are differences, but nothing that I have noticed that would make an enterprise shy away from it.
A more major hurdle, in his opinion, concerns third-party add-ons. Although both products support quite a few third-party extensions, they're not all the same ones. Firefox has more than 400 to choose from. Linky, for example, lets the user open or download all or selected links, image links and even web addresses found in the text in separate or different tabs or windows. Conversely, IE has many add-ons you won't find in Firefox.
"Issues will come up all the time due to a dearth of plug-ins for the likes of Flash and Acrobat," says Collins. "If you are attempting to use Firefox with Outlook Web Access, you may encounter difficulties as they work differently."
He outlines an example: setting up a meeting/appointment. This is simple in IE, but in Firefox there has to be at least one invitee. This can become as bizarre, he says, as having to invite yourself and then responding to the invitation.
In the area of enterprise management capabilities, too, Firefox comes in a distant second.
"Organizations are likely to prefer a browser that has admin tools that tie into existing systems for code maintenance and configuration management," says Valdes.
