Yesterday Mozilla released Firefox 11 and also started development on Firefox 14. The unique aspect of version 14 of the Firefox browser is that it will be the Metro UI based Firefox for Windows 8.Mozilla's has adopted a rapid release schedule to compete with Google's Chrome and major versions are released very quickly as a result. While this results in fewer new features in each release it also means that bugs are irradiated quickly.
Firefox 14 is still in a very early stage of development abnd doesn't feature any Metro features, but this should change as the product evolves. Mozilla has shared their update schedule which expects the final version of Firefox 14 to be available by July this year.
