Fira Sans (initially called Feura Sans) is a humanist sans-serif typeface designed by Erik Spiekermann, Ralph du Carrois, Anja Meiners and Botio Nikoltchev of Carrois Type Design for the Firefox OS. Fira was released in 2013 initially under the Apache License and later reissued under the SIL Open Font License. It is closely related to the Meta typeface designed and developed by Spiekermann in the late 1980s which is used as the brand typeface of the Mozilla Foundation.
In its initial 2013 release, Fira Sans was available in four weights with corresponding italics: light, regular, medium, and bold. In May 2014, the number of weights was increased to 16.
Fira Sans is accompanied by a monospaced variant called Fira Mono, available in regular, medium, and bold.
