Please see the page with technical details to learn exactly what the browser supports, and what it doesn't support. 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. This means that this browser, however extremely close to Firefox, does not have all the functions that Firefox has. 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. Make sure to get the most speed out of your browser! That needs to change! So, here is the Pale Moon project: Custom-built and optimized Firefox browsers for Windows Operating Systems. 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.
