Lifehacker gave it a strong review
and it looks like its just a recompile of the browser using a C compiler optimized for modern operating systems / processors.
I'm a little disappointed they didn't go with a fully GPL'd license like IceCat (http://www.gnu.org/software/gnuzilla/
) but I realize that's a little more complex than they probably want to get into. Unfortunately, its not clear about what license they're using and many sites are reporting it as "freeware", although its pretty clear its MPL (http://www.palemoon.org/technical.shtml

This also means that, under the MPL (Mozilla Public License), it suffices for me to provide a link to the Firefox source code as published by Mozilla, since no program code in it was changed (although some parts of the source tree were edited to selectively disable certain parts of the browser - this has been limited to conditional directives in header files and makefiles).
The author has edited the sources a bit but hasn't published the modified headers and makefiles. Pale Moon is within the grey area between open and closed source.
Edit: Does seem to still be saving data to C:\Documents and Settings\USER\Local Settings\Temp folder, so clearly not stealth, but I'm not sure its still saving to AppData.
3. The browser creates directories under %APPDATA%\Mozilla, specifically Mozilla\Extensions
These directories are related to the underlying Mozilla extension code. This issue is completely harmless and non-breaking; in fact, having (all) Mozilla-based applications use this one central location for extension IDs is desired.

Should I add it?
I think yes. I'll vote Pale Moon if you add it.
