In the spirit of openness and to ensure contributors stay up to date on Firefox updates, here are a few key resources you can use to find information about Firefox releases (both desktop and mobile).

Firefox Train Release

The Firefox Release team maintains a platform that outlines Firefox regular release schedule (also known as the train release). You can find more information at: https://whattrainisitnow.com.

Release Information, Support Articles and Community Updates

For each Firefox release, we maintain a wiki page that compiles official release notes, relevant support articles and community updates. This page is a helpful reference that can help you stay informed about what's new, what's changed, and what issues may have been resolved or introduced. To find out more, please go to: https://wiki.mozilla.org/Support:Releases.

Firefox feedback and bug boards

To help us identify trends and stay on top of user-reported issue, we use the following Trello boards to track Firefox feedback and bugs (for both desktop and mobile). These boards are managed by the Support Operations team and serve as a centralized place to collect, organize and monitor issues surfaced across SUMO channels.

By tracking this information regularly, we can better highlight recurring problems and provide more valuable insights to the product team. Here are invitations to join our Trello boards:

• Feedback board: Firefox Feedback Board 2025
