Fluent for localizers

Fluent is a localization system, previously known as L20n, designed at Mozilla to unleash the expressive power of the natural language. The format used to describe translation resources used by Fluent is called FTL.

This section of documentation includes a brief introduction to Fluent’s syntax for localizers and covers specific details regarding Mozilla’s implementation (branding rules, additional functions available in Gecko, etc.). For a detailed overview of Fluent, consult the official documentation.
