Eclipse r3dfox, a modern Firefox based web browser for Windows Vista and 7!

r3dfox or r3dactedfox is a fork of release branch Mozilla Firefox made for Windows Vista, 7, and 8. r3dfox also comes with limited compatibility for Windows XP using One Core API. The main goal is to be similar to stock Firefox while providing Vista+ compatibility as a fork point. However there are also some additional tweaks and adjustments.
