Tempicon.png Firefox Platform 2015 Roadmap
Owner: Martin Best Updated: 2015-07-16
This roadmap outlines the current direction for Firefox Platform development through 2015. The following document is subject to change at anytime. It is also not a commitment to ship a features but rather an intent to implement and land them on by default in the nightly version of Firefox unless otherwise stated.
