Mozilla confirmed that it is still working on a Windows 8 release of Firefox that will run under Metro, but was unwilling to offer a timeframe for when this might become available.

"The team is at work building a browser for the Metro environment, but we don't have new test builds to share at the moment," a Mozilla spokesperson told The INQUIRER in a statement.

"Our plan is to have a single Firefox executable that will offer users both the classic browser interface as well as one tailored for Metro."
