Why settle for a basic build of your Firefox browser on Windows Operating Systems when you can have one that performs 25% faster? Mozilla does not provide optimized browser packages for Windows, while many Linux ("from scratch") users get the advantage of a browser built specifically for their system. That needs to change! So, here is the Pale Moon project: Custom-built and optimized Firefox browsers for Windows Operating Systems. Make sure to get the most speed out of your browser.

Of course, getting a faster browser is not just about optimizing the compilation process (building a program from its source code), but also about carefully choosing features and how to choose the best setup. This means that this browser, however extremely close to Firefox, does not have all the functions that Firefox has. A few, carefully selected, features have been disabled that are not in high demand, and that do not interfere with the way web pages are displayed or function; all to maximize speed and efficiency of the browser. Please see the page with technical details to learn exactly what the browser supports, and what it doesn't support. In short, if you need accessibility features or parental controls, then please visit the firefox homepage and get the official, non-optimized build.

Features:

  • Highly optimized for current processors
  • 100% Firefox sourced: As safe as the browser that has seen years of development.
  • Uses slightly less memory because of disabled redundant and optional code
  • Significant speed increases for page drawing and script processing
  • Support for SVG and Canvas
  • Support for Firefox extensions, themes and personas

What's New:

  • Added a "Firefox compatibility mode" selection in Options -> Advanced.
  • This mode is enabled by default (reluctantly so), because too many websites (including some very big players who, themselves, promote an Open Web...) still use very poor browser detection methods based on arbitrary User Agent string comparisons, not catering to alternative browsers, and the resulting user experience being poor (being presented with mobile site layouts, broken pages, or even being flat-out refused service because someone exercises freedom of choice for web browser used). This should alleviate most, if not all, issues with browser-discriminating websites.
  • Improved active tab display on particularly dark personas.
  • People using "black" personas/lightweight themes should now have a lot less difficulty distinguishing the active tab.
  • Disabled SSL 3.0 by default (to put a muzzle on the POODLE).
  • Please note that this may cause issues with some poorly configured web servers (usually ones with a hopelessly broken security setup that do not support TLS 1.2 or secure (re)negotiation of the protocol).
  • Fixed add-on update issue (that was preventing update checking through addons.palemoon.org).
  • Fixed the redundant redundancy in asking redundantly if the browser would be allowed to ask to install an extension when not on addons.mozilla.org.
  • Fixed the internal UA-sniffing insanity that broke devtools in a few different and colorful ways.
