[1][2][3][4] The typeface was originally commissioned by Telefónica and Mozilla Corporation as part of the joint effort during the development of Firefox OS.

With the name “Fira,” Mozilla wanted to communicate the concepts of fire, light, and joy, but with connotatively agnostic language intended to signal the project's global nature.

[11][12] FiraGO is a multilingual extension of Fira Sans that includes Arabic, Devanagari, Georgian, Hebrew, and Thai letters, in addition to Latin, Greek, and Cyrillic alphabets in the typeface.

In 2016, the development of FiraGO was initiated after geo data provider Here Technologies selected Fira Sans as their corporate typeface,[13] but needed the typeface to be usable for “broader language applications, especially in map applications.”[14] Subsequently, Here Technologies commissioned bBox Type GmbH for a global script extension to Fira Sans, which was expanded into FiraGO project.

Based on Fira Sans 4.3, FiraGO was released as a separate product, and will be the main font family in the group.
