Make sure to get the most out of your browser!

The browser supports legacy Firefox extensions, ensuring backward compatibility while also fostering a community-driven development ethos.
With its focus on simplicity and control, Pale Moon targets users who prioritize lightweight software over the resource-heavy, mainstream browsers of today.

User Interface
Pale Moon’s user interface is a throwback to the pre-Australis days of Firefox, offering a more traditional and functional design. Tabs, bookmarks, and toolbars are highly customizable, and the layout is uncluttered, emphasizing usability over aesthetics.
