There's an issue with the MSIX (Microsoft Store) install of Firefox, creating a web app doesn't add a shortcut in the start menu nor is the web app shown in the Windows search... This has been an issue since it released for the Microsoft Store versio...
I agree with you. But for now, this is what you can do:Start > All > Scroll to 'Firefox web apps' folder > Right-click a web app > More > Open file location.You'll be able to rename or delete the shortcuts.
