Goanna (software)

Goanna is an open-source browser engine that is a fork of Mozilla's Gecko. It is used in the Pale Moon browser, the Basilisk browser, and other UXP-based applications. Other uses include a fork of the K-Meleon browser and the Mypal browser for Windows XP.
Goanna as an independent fork of Gecko was first released in January 2016. The project's founder and lead developer, M. C. Straver, had both technical and trademark motives to do this in the context of Pale Moon's increasing divergence from Firefox.
There are two significant aspects of Goanna's divergence: It does not have any of the Rust language components that were added to Gecko during Mozilla's Quantum project, and applications that use Goanna always run in single-process mode, whereas Firefox became a multi-process application.
