Translation ---------------------------- Why are things like Fluent Design, Windows features like Notifications, Timeline, Sets, Sharing functions etc. not supported? Edge is increasingly becoming a serious competitor. Although Firefox has received an optical makeover, unfortunately this does not fit with modern designs such as Windows 10. Furthermore, many system specific things are simply not supported. Why? --------------------------------------------------------- Firefox is not Edge nor is part of the operating system. Very straight forward answer to a non-specific question, also Microsoft makes it as difficult as possible for Firefox. If you are looking for something specific please ask.
