Firefox App Localization (no longer supported by Mozilla Corp staff )

The Mozilla Tech Evangelism team is no longer monitoring or approving language requests from localizers and we’ll no longer be accepting new app projects from open web app developers. Localizers should be aware that most of the web apps listed here have not been updating their apps with new localizations. When this pilot began two years ago our aim was to provide a platform where open web app developers could connect with volunteer app localizers from regional communities. Dozens of developers uploaded their app projects and hundreds of volunteers contributed translations in over 100 languages. In fact, we had more interest and engagement from translators than our developers could keep up with. Huge thanks to everyone who translated strings and reviewed translations. Your contributions have helped deliver new apps to your language communities around the world. If you are seeking new localization tasks to support and build the Firefox Marketplace community in your language, take a look here: If you are an app developer with an existing project, please check your project for all complete localized files, package them up with your app, and resubmit to Marketplace with the new locales enabled and the new localizers credited. Thank you all for bringing choice to Firefox OS app users.
