Hi, Quoting ArchWiki:     The AUR and official repositories are intended for packages which install general software and software-related content, including one or more of the following: executable(s); configuration file(s); online or offline documentation for specific software or the Arch Linux distribution as a whole; media intended to be used directly by software. This package does do unique features. Including sandboxing, discrete GPU wakeup prevention, background process monitoring, and rewriting the .mozilla directory location. The latter of which is similar to what firefox-xdg does. -- Sincerely, Kimiblock
