Localize Mozilla

If you want to make Firefox available in your language, join a global community of localizers from all over the world, track progress of various Mozilla localization projects, and more, Pontoon is there for you.

Here's why localizing Mozilla matters.

We are committed to an internet that includes all the peoples of the earth — where a person’s demographic characteristics do not determine their online access, opportunities, or quality of experience.

The Mozilla Localization effort represents a commitment to advancing these aspirations. We work together with people everywhere who share the goal to make the internet an even better place for everyone.

This is how it works.

Pontoon is a simple and intuitive tool that requires little technical skills to use it. Each language has its own team of localizers. Join one, find a project you'd like to contribute to, and you're ready to start contributing!

  1. Pick your team and project
  2. Submit a suggestion
  3. Have it approved by a trusted localizer
  4. Show it to your friends as it lands in product

Things which make it special.

From the ground up, Pontoon has been designed as the tool that brings all your team's localization tasks together in one place. All the functionality and services you need are seamlessly integrated into a single platform.
