Basilisk was first announced in 2017 by the developer behind
Pale Moon, M.C. Straver, as a fork of Mozilla Firefox in order to serve as a basis for the Unified XUL Platform, with the developer calling it a "reference application for development of the XUL platform." The Unified XUL Platform is a fork of the backend of Firefox before version 57, which the developer forked because it dropped support for classic Firefox extensions,
XUL, and
XPCOM. Because of this, it uses the same rendering engine as Pale Moon,
Goanna, which is a fork of Firefox's
Gecko rendering engine. The browser was later released on December 17, 2018. The browser was able to use WebExtensions and classic Firefox addons, but the support for WebExtensions was dropped in 2019. M.C. Straver announced on the Pale Moon forums that he was ending support for the web browser in 2021 as it had become redundant to Pale Moon and offered it for sale. The rights were purchased and development was later picked up by a developer under the name of Basilisk-Dev in 2022. The browser remains open source. == Features ==
