hello dandy, i know of no ongoing development or efforts by mozilla of porting firefox to the windows phone platform. <br>originally there have been technical and legal hurdles in the app store which discouraged mozilla from starting any developments in this direction. i don't know about the current situation, but since mozilla is now focusing its energies on creating firefox os as open source web-based platform, i doubt that you will see firefox on your windows phone device in the foreseeable future...
