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

  • 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

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)
