Mozilla Scraps Firefox for Windows 8′s Metro - March 15, 2014

Mozilla has ordered its teams of engineers to halt all future development of Firefox browser for Windows 8 Metro because of low adaptation of ‘the Metro’ platform by Windows users.
Mozilla first noted a Metro version of Firefox was coming back in February 2012 and revealed a prototype in April 2012. The company then showed off a pre-release of Firefox for Windows 8 in October 2012 and offered a Nightly build in February 2013.
