Microsoft today again defended that decision.
"The developer community has been vocal that they want to push the Web forward," a Microsoft spokesman said in an e-mail. "The browser is only as good as the operating system it runs on and a browser running on a ten-year-old operating system tethers the Web to the past. The time has come to stop focusing on lowest common denominator, and to really push what's possible with innovations like full hardware acceleration."
Some Mozilla developers have used stronger words to describe Microsoft's argument that IE9 is the best browser on Windows.
"Microsoft's message that IE9 is the apex of what a browser can do with the GPU is nonsense," said Robert O'Callahan, a New Zealand employee of Novell who works full time on Mozilla's graphics infrastructure. In a post to his personal blog, O'Callahan said, "Microsoft's PR about 'full hardware acceleration' is a myth."
Mozilla technology evangelist Asa Dotzler was even more blunt. "Microsoft, stop making bull**** claims about hardware acceleration," Dotzler titled a post to his personal blog two weeks ago.
