Is IE9 a modern browser?

Mozilla evangelist Paul Rouget laid out a comparison of standard support for IE9 and Firefox 4, which convincingly proves that IE9 is lagging behind in many ways. Something in which this browser loses even Firefox 3.5, released two years ago, not to mention Google Chrome and Opera.

With a special cynicism, Rouge designed the note so that in IE9 it is rendered incorrectly .

For comparison, we also provide indicators of other browsers and test results referenced by Microsoft itself.
