March was a big month for Web browsers, with major new versions of both Internet Explorer and Firefox. Both browsers have been suffering in the browser wars; Internet Explorer has steadily declined from its near-total monopolization of the browser market, and Firefox's growth has faltered, most likely due to strong competition from Google's Chrome.
Worldwide Browser Market Share
With Internet Explorer 9 out for just two and a half weeks, and Firefox 4 available for only nine days, however, not much has changed so far. Microsoft's browser continues to shed market share, dropping 0.85 points to 55.92 percent. Firefox is essentially unchanged, at 21.80 percent. These new browsers may yet be influential in encouraging people to switch—but at the moment, it looks like the only people adopting them are users of older versions.
