What is SUMO?
With more than a hundred million users around the globe, Firefox is no longer a web browser used by just the tech savvy people. While we have seen tremendous community efforts to provide support for Firefox through the years, the resources have been scattered and hard for our users to find. The need for a centralized and official support channel has never been greater, and Sumo is Mozilla’s attempt to meet that need.
SUMO is short for support.mozilla.com, the official, community-powered support website for Mozilla Firefox. At its core, SUMO is a wiki, which means anyone can help writing or improving content. Find out more about how you can get involved!
