Google today released a plug-in that embeds its Chrome browser into rival Microsoft's Internet Explorer, a move one analyst said may be an admission by Google that getting users to switch is harder than it anticipated.
Dubbed Google Chrome Frame, the open-source plug-in can be used with Internet Explorer 6 (IE6), IE7 and the newer IE8, said Google in a blog post introducing the new software.
"One challenge developers face in using these new technologies is that they are not yet supported by Internet Explorer," said two Chrome engineers and a Chrome product manager on Google's Chromium blog . "Developers can't afford to ignore IE -- most people use some version of IE -- so they end up spending lots of time implementing work-arounds or limiting the functionality of their apps," said Amit Joshi, Alex Russell and Mike Smith, all of Google.
The three were right about IE's popularity: According to the most recent data from metrics firm Net Applications, IE accounted for 67 percent of all browsers used last month. Mozilla's Firefox, at No. 2, held a 23 percent share, while Chrome owned just 3 percent of the market.
Developers can tell IE to flip the switch to Chrome Frame with a single HTML tag on their sites or in their applications' HTML code. Users, however, must install Google Frame manually.
Although Google portrayed Chrome Frame as a boon to developers and users -- "We believe that Google Chrome Frame makes life easier for Web developers as well as users," said Joshi, Russell and Smith -- others speculated today that the move might be a way for Google to sneak into systems now running only IE.
Sheri McLeish, an analyst with Forrester Research, saw it differently.
"Google's realizing that the potential to get people to move off IE is harder than it thought," McLeish said. "Clearly, Google is gunning for Microsoft in all its business, but this is an unexpected path to take for what seemed like an effort on its part to offer a full alternative to IE."
In McLeish's eyes, in fact, Chrome Frame, while good news for developers and even users, is an admission by Google that it won't be able to tempt many IE users, especially those running it within enterprises, into switching.
"It might give Google more exposure within an enterprise setting, where it lacks the kind of administrative tools that Microsoft offers for IE," she said, "but what's the motivation for people to migrate to Chrome when they can get some of its benefits within IE? I think its message to get people to migrate is actually decreased. I'm just not sure where Google is going with this."
