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!
Pale Moon is a middle road, cutting away support for (by current standards) ancient systems to give you a browser that not only supports the wide variety of uses the Mozilla Firefox browser offers, but also uses the capabilities of modern hardware to give you a fast, efficient browser. Using Pale Moon, you will not be wasting processor time on inefficient code that is designed to run on hardware that is more than 15 years old. If you have an Athlon XP or later CPU, or a Pentium III or later, then this is the browser for you!
Note that this version is no longer maintained or supported.
Highly optimized for modern 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
