Though Windows 8 has now been out for a year and change, there's still no Firefox browser dedicated to its tile-y interface. That situation's not improving, as Mozilla has just announced that its 'Metro' Modern UI-look version has been further delayed to March 18th. We were expecting it to arrive this month following delays that have plagued it since it was first announced nearly two years ago. However, the team pushed back all Firefox releases for two weeks to let workers enjoy the holidays, which didn't help matters. If you're feeling brave, you can still check it out by downloading one of the nightly builds, but judging by the logs, you'll still need to dodge a lot of bugs.
