|pagetitle=Firefox Platform 2015 H1 2022 Roadmap|owner=Martin BestAndrew Overholt|updated=December 2014March 2022|status=DraftComplete|description=This roadmap outlines the current direction for Firefox Platform development through 2015the first half of 2022. The following document is subject to change at anytime. It is also not a commitment to ship a features feature but rather an intent to implement and land them on by default in the nightly version of Firefox unless otherwise stated.}}
