Pale Moon Web Browser

Pale Moon is a web browser for Microsoft Windows, based on the Firefox source code. It aims to be somewhat lightweight and provide a familiar interface to Microsoft Windows users. Pale Moon is a fork of the Firefox web browser. It retains the XUL user interface and all functionality of Firefox, while removing the dependency on Gecko and substituting it with a layout engine called Goanna.

Pale Moon is available in two versions: a regular version and a Firefox-based Developer Edition. The Developer Edition is based on the regular version, but with additional software development tools added, including a source code editor, debugger and inspector. The Developer Edition is also pre-configured to display pages in a mobile device layout.
