Firefox has made a lot of progress over the years, and lately, Chrome has been picking up market share almost every month. But Internet Explorer remains the most-used Web browser in the world, and for that reason, it’s quite significant that the fourth Platform Preview of Internet Explorer 9 has been made available to developers.
Dean Hachamovitch, a general manager at Microsoft, wrote a very long post on the IEBlog to announce this move, and there are lots of pictures, charts, and graphs – along with a video – to document how everything will appear and perform. It’s well worth a look.
He wrote, as well, “With this installment, you will find more performance and more support for same markup. You’ll also find many fixes to issues reported in previous Platform Previews.”
Best to get familiar with this stuff ahead of time, because within a day or two of its release, Internet Explorer 9’s almost guaranteed to attract millions upon millions of users.
