This is an overview of the current Firefox OS product roadmap. Information on this page is subject to frequent updates and changes.

Feature Complete Dates

FC means Feature Complete. At this date, a development package is made available to chipset and hardware manufacturers to stabilize the release for productization.

  • FxOS 2.2 Feature Complete date: April 29, 2015 [completed]
  • FxOS 2.1 Feature Complete date: Oct 13, 2014 [completed]

Disclaimer: Future Feature Complete dates are subject to change, based on changes in commercialization and business demands.

The current planning is to continue with FxOS releases every 12 weeks, aligned with the Firefox/Gecko release trains. At any given time master is open for feature development and in parallel converging one release for productization.

Feature Backlog

We maintain a backlog [1] of features for Firefox OS. Our engineering community of Mozilla engineers, partner engineers and contributors pick and prioritize features from this backlog. Please request access to view this doc. To propose additions to the backlog, please contact ffos-product@mozilla.org.

Upcoming Releases

For each of our upcoming releases, we have defined a selection of focus areas which highlight expected product features and enhancements. The team is confident many of the features in these focus areas will make the feature complete dates for each respective release. However, it is possible that the set of features that land at the end of a release cycle can be impacted by market/partner demand.
