Is IE9 a modern browser?

    Mozilla evangelist Paul Rouger has uploaded a comparison of standard support for IE9 and Firefox 4, which convincingly proves IE9 lags in many ways. In some ways, this browser even loses to Firefox 3.5, released two years ago, not to mention Google Chrome and Opera.

    With particular cynicism, Rouget designed the note in such a way that it renders incorrectly in IE9 .

    For comparison, we also provide indicators of other browsers and test results, which Microsoft itself refers to.
