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.

The Pale Moon browser has the following features:
* Specifically optimized for current processors. It makes full use of the enhanced
instruction sets of newer CPUs - as a result, this browser will not run on older systems
Uses a little less memory than the official builds because of the disabled features (listed below) go & see
Supported processors see fist most new ok.
386 / 486 / Pentium / Pentium II / Pentium III ( NO )
I been testing it for a few week & it is faster and all add-ons work so far just go get the firefox add-on as you need, & hope you like it.
