## Description

Pontoon Add-on brings Mozilla Pontoon directly into your browser, helping localizers stay notified and productive. Receive real-time notifications from Pontoon, use built-in proofreading helpers, and report or fix bugs without leaving the page. An interactive introduction tour guides you after installation so you can start contributing quickly.

Designed for translators and localization teams, the extension streamlines common l10n tasks and improves workflow efficiency. The project is open source—ideas and issues are welcomed on the GitHub repository. A Chrome version is also available for cross‑browser use.
