Build Status

Transvision is a Web application targeting the Mozilla localization community, created and maintained by the French Mozilla community (

The main purpose of Transvision is to provide a specialized search engine to find localized strings in Mozilla code repositories for all Mozilla products (Firefox, Firefox for Android, Firefox for iOS, Focus for iOS, Focus for Android, Thunderbird, SeaMonkey) and websites (currently only is supported) via a Web interface. There are also side-features such as checks for common typographical errors for some languages or validity checks for localized access keys in the UI).

Transvision is written in PHP, the string extraction is done with the compare-locales library (Python) and server install/maintenance scripts are in Bash.

Transvision is available at:

Transvision Beta is available at:

Transvision was created by Philippe Dessante, from the French Mozilla localization team.

Full Installation (production or heavy development)

  1. Fork the Transvision Project into your GitHub account.
  2. Clone your fork to your machine.
  3. Copy app/config/config.ini-dist to app/config/config.ini and adapt the variables to your system.
  4. Run first app/scripts/, then app/scripts/ This process will take some time as it downloads several repositories (~2GB of data).

To bound PHP internal web server to use -remote: the server will be accessible from other devices on the LAN, or from the host machine in case Transvision is running inside a virtual machine.

Snapshot installation (regular development)

  1. Fork the Transvision Project into your GitHub account.
  2. Clone your fork to your machine.
  3. Run ./ This process may take some time as it downloads a snapshot of data from Transvision server (~400MB). It will also download Composer, the PHP dependency manager, and install the dependencies needed. A config file located in app/config/config.ini will be created automatically. Once this is done, PHP development server will be launched and you can visit http://localhost:8082/ with your browser.
