When Internet Explorer 7 was released, there was speculation that it would end up taking some of the market share away from Firefox who had been experiencing growth at the time.  Well, 100 million installations of IE7 have occurred and Firefox hasn’t lost any of their market share.  In fact, they have continued to grow over the last three months. Firefox currently has 14% of the market!

So, with 100 million installations of IE7, were they all originally Internet Explorer users? Well, yes, most of them come at the expense of IE6.  The new browser is just being exchanged for the older version.  Tony Chor, an Internet Explorer group program manager says “As of January 8th, we had the 100 millionth IE7 installation.  We expect these numbers to continue to rise as we complete our final localized versions, scale up Automatic Updates distribution, and with the consumer availability of Winnows Vista on January 30, 2007.”

It will be interesting to see what will happen with the Windows Vista launch and if previous ‘basic’ Firefox users will just stick to IE7.  There are many Firefox users who don’t realize the capability that it has, or who choose just to use it for its’ basic features liked the tabbed browsing.  Now that IE7 has the tabbed browsing, some of those basic users may decide that they don’t need to download Firefox. 

While there may be some people who, through Automatic Updates , or with an upgrade to Windows Vista will stick with Internet Explorer 7,  I believe there will be that many more new people that discover Firefox for the first time which will at least keep the market share at 14% or will help it continue to grow.
