I found this on their page this a.m. while checking out the site. Isn't it just the same as Firefox? I'm not an expert on these gadgets.

Welcome to the Pale Moon project homepage Pale Moon is an Open Source, Firefox-based web browser for Microsoft Windows, focusing on efficiency and ease of use. Make sure to get the most out of your browser!

The Pale Moon project is the work of a single individual (Mr. M.C. Straver), using contributed Open Source code to create a full-featured, speed optimized browser based on the popular Firefox browser.
...
Users will find a slightly more conservative approach to changes in the user interface in the Pale Moon browser, which, although very close to Firefox, is (now more obviously so than before) a different product.
...
Pale Moon will be updated only for select and relevant updates of the Firefox base source code and otherwise develop independently on the chosen version of the Gecko engine.

It is built on the same open source engine as Firefox but different people.
