The Pale Moon browser is open source and free software.

but you have access to the source code and may modify and redistribute
our software subject to certain restrictions. Our source code is for
the most part covered by the Mozilla Public License v2.0, but various
parts and libraries included in the browser carry different licensing,
and as a whole this project has a hybrid licensing model which is
governed by various licenses outlined in about:license in the browser
itself. Please make sure you understand the licensing involved before
publishing derivative works.

we strictly enforce our trademark (™)

the marks to commit fraud. Our trademarks include, among others, the
names Pale Moon™ and "Your Browser, Your Way"™, as well as the Pale
Moon™ logo, Goanna™
name and logo, Goanna Runtime Environment™, GRE™ and other project and
product names. This means that, while you have considerable
freedom to redistribute and modify the software's core code, there are
restrictions on your ability to use the names and logos in
ways which fall in the domain of trademark law, even when these
trademarked names and assets are included in
the source tree and built into
binaries that we provide for distribution.
In addition, we do use some of Mozilla's trademarks in our

Executable software binaries of core products released by
Moonchild Productions, such as Pale Moon, are made available under the
terms of the binary redistribution license.

different licenses like the Pale Moon
