Overview

Firefox for Android roughly follows the Firefox Gecko release schedule. This means we cut a Beta every 4 weeks, with a full cycle (~4 weeks) of baking on Beta before going to Production release.

The Firefox for Android release schedule contains more details related to specific Mobile handoffs.

Firefox for Android Release

There are two releases this covers: the current changes in the Fenix Nightly channel that is going out to Beta, and the current Beta that is going to Production.

Cutting a Beta

• Review FeatureFlags to determine if there are features that need to be enabled (or disabled) for Beta and Production release of Fenix. This will be a discussion with PO, PMs, EMs.
• Make a new Beta: Follow instructions here and notify the Release Management team (slack: #releaseduty-mobile). QA team is notified that a Beta release has been captured and they will run tests for Beta release sign-off
• Once there is GREEN QA signoff, the Release Management team (slack: #releaseduty-mobile) pushes the Beta version in the Google Play Console
• Check Sentry each day for issues on Firefox Beta and if nothing concerning, Release Management team bumps releases to 25%. Subsequent Beta builds are bumped to 100% assuming no blocking issues arise.

Bugfix uplifts / Beta Product Integrity

• If bugs are considered release blocker then find someone to fix them on main and the milestone branch (cherry-pick / uplift)
  • Add the uplift request to the appropriate row in the Uplifts document. Ask for approval of uplift from Release Owner amedyne and then notify Release Management team (slack: #releaseduty-mobile) of the uplift changes
• Note: Beta release versions are captured at least once a week during the Beta cycle.

Production Release Candidate

• Production Release Candidate is captured on the third week of Beta by the Release Management team (slack: #releaseduty-mobile). This is then sent to Quality Assurance for Production Release Testing Sign-off.

Production Release

• Once there is GREEN QA signoff, the Production Release Candidate is pushed to the Alpha testing track in Google Play Console by the Release Management team (slack: #releaseduty-mobile)
• If nothing is concerning, release management officially tags the Release Candidate as Production release, (usually 1 week after 1st Release Candidate)
• Check Sentry for new crashes. Follow instructions for Crash Monitoring. File issues and triage.
• If nothing concerning, release management bumps releases(5%, 25%, 100%)
