About Release Management
The Release Management team keeps the release process on track for upcoming releases. We focus on release quality, security, and stability. As release managers follow specific features and individual bugs, we work with developers, engineering managers, product managers, UI/UX teams, QE, and release engineering, doing whatever it takes to coordinate the many details in the creation of a new version of Firefox. We aim to get features & fixes landed in time for proper evaluation. Our goal is to ship the most stable & excellent product possible for Firefox Desktop & Mobile for our users.
There are many ways to help the release management team. Help with tracked bugs, or hack on the tools our team develops and maintains.
Developers and anyone in the community can help by proposing bugs for tracking, using the tracking flags in bugzilla.mozilla.org.
The relman team maintains several tools. You can help by fixing bugs!

We host and are a part of number of meetings. You can't miss us at channel meetings, where we discuss and try to resolve any release related issues. Anyone working to get a new feature or complicated fix into Firefox may want to join the channel meeting to discuss the process with the entire team of release managers. User advocacy, QE and stability, and release engineering team members also often join the channel meetings.

When the release schedule is adjusted for any reason, we need to ensure that our calendar is updated to reflect this. If the calendar itself is updated, there is a link to it on this page (at the top) as well as on the release calendar.
Each version of Firefox is followed by a release manager who owns it from start to release. This way, Nightly, Beta, ESR, and Release channels have someone dedicated to getting all the pieces put together correctly.
