PC users have long enjoyed freedom over installing whatever web browser they want on their Windows machines, but things may work differently with Windows 8 tablets. According to a Mozilla blog post, only one browser, Internet Explorer is allowed to run in Windows classic mode on ARM-based tablets. That means no third-party browsers such as Google Chrome or Mozilla's own Firefox. However, switching to the slick Metro UI gives users more flexible browser options - you can install any compatible browsers in this mode.
Deputy General Counsel David Heiner explains that the company couldn't allow other browsers to run due to the new requirements and security needs of its upcoming tablets, which apparently only Microsoft's Internet Explorer is equipped to handle. Both Google and Mozilla are understandably upset over Microsoft's decision. Harvey Anderson of Mozilla's legal division commented that "sometimes [Microsoft] need some pressure... If it turns out to be legal pressure, that could be the thing."
