I use Mozilla Firefox as my browser of choice. I do this because I like all the plugins and the tabbed browsing. I assume that due to the great functionality and ease of use of Firefox, that a lot of other people also use it, but it turns out I was wrong. In an interesting study of site traffic from Site Pro News, it turns out that Internet Explorer is still king.

Over 58% of internet users use some version of IE. 33% are using Firefox, but this figure may be a little skewed, as most of the people visiting Sitepronews are industry insiders and marketers. If you were to track browsers on a retail site, the proportion using IE would be a lot higher. So if your site resolves really well on Firefox, but not so well on IE, you need to fix it. It could be losing you business.
