"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, meaning you may be losing speed and efficiency when you use your browser; and truth be told, most people use their browsers all the time! 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 and efficiency out of your browser!"
