For example, I still have Firefox in the Menu after removing, when I click the icon I get Launching Firefox (failed) You are not authorized to execute this fire.
sudo pacman -Rns firefox
error: target not found: firefox

This would require that pacman notify us or manually regenerate the app database itself whenever it installs or removes any GUI apps with .desktop files. That's how this works; the menu itself can't be constantly polling for changes or else it would consume excessive system resources. Please report this to the Arch developers. Thanks!
