Pale Moon is an open source web browser forked off from Firefox, focusing on efficiency and ease of use, by leaving out unnecessary features, making optimizations, and having a fully customizable user interface, while maintaining compatibility with many Firefox extensions as well as its own extensions and themes.

IMPORTANT: We will no longer be using SourceForge from this point forward and will provide updates through our own site:

Pale Moon provides a familiar set of controls and visual feedback similar to previous (pre-Australis) versions of Firefox, including grouped navigation buttons, a bookmarks toolbar that is enabled by default, tabs next to page content by default, and a functional status bar.

This is a third party build with close development cooperation with the original Windows builds; the original project is at -- For support, check our forum at

    It would be a GREAT browser if not by a single thing: every time you open the browser and go to a site pale moon downloads around 2 MB of data of an unknown source even if you got no extensions and the auto-update feature is disabled, this problem was already reported to the developer and he didnt care to investigate, the same happens with firefox and chrome based browsers, this doesnt happen with IE and Opera. Maybe someone here on majorgeeks knows why that happens and what that source is, if more ppl including the owners of this site report this to him maybe he'll do something about that. Btw, the pic of pale moon here is outdated, it got a new GUI now. Also, it doesnt remove the tools that are used only by developers which would be much better as an extension.

    This is what every other browser should have, a stripped down version alternative. Palemoon is fast and is breathing new life into my aging computers. It would be good to have it on OSx.

    I want to thank all the folks who recommended Pale Moon. I’ve just been fed the f**h up with FF because of all of the memory leaks, etc. I've been running v16 forever because whenever I’ve tried to upgrade to newer versions, they’d all pretty much just crash after 30 minutes of heavy use, and not a single version of FF that I’ve ever used has ever fixed the memory leak problems. Not a single one. I actually installed a tiny batch file on quicklaunch so I could quickly kill FF at the point it’s consumed all of my RAM so I could then start over with “Restore Session” to automatically reload all of my previous tabs. After trying every “solution” to the leak problem, that’s the only one that ever did in any good for me. Apparently the arrogant tards at mozilla would rather tweak the UI to death rather than make a browser that actually works. They’re worse than even Microsoft because Microsoft has to listen to their customers sooner or later or go broke. Nonprofits can just drift along forever. At any rate, I just finished installing PM, including importing everything from FF with their little importer program, and everything went flawlessly, including all settings and the plethora of add-ons I use. The only difficulty was getting roboform attached, which I can’t live without. I did finally dumb around and got the roboform taskbar program to attach roboform to PM, which then worked flawlessly. It is, however, necessary for the roboform taskbar program to run all time for roboform to continue to work on PM, but this is a small price to pay to ditch FF forever. I've used PM for a week now, opening/closing/keeping hundreds of tabs, and I’ve been stunned at how much faster PM is than FF, as well as the VERY small memory footprint occupied by PM vs FF. Even after a week's HEAVY utility, PM has not grown beyond 1 GB, and even better, when I close tabs, ALL of the RAM is given back. Basically, PM is what FF ought to be, and even better, the genius behind Pale Moon, Mark Straver, has committed to keeping the PM UI fundamentally unmolested. I’ll be installing PM instead of FF on all of my client’s computers in the future as well!

    A perfect browser: fast, no crashes. Replaced Seamonkey with Pale Moon on Puppy Linux.
