Everything is fine except for the Alt Tab Switcher
Distro: elementaryOS 6.1
AltTab Switcher: Catts
Scaling factor: HiDPI(2x)

@Tzolkin I have the same problem on Elementary 6.1 I'm becoming crazy 🤣

This worked for me until a couple of days ago.

StartupWMClass="firefox-aurora", "Firefox Developer Edition"

I'm now running version 99.0b7 and it seems to work with

StartupWMClass="firefox", "Firefox Developer Edition"

Everything is fine except for the Alt Tab Switcher Distro: elementaryOS 6.1 AltTab Switcher: Catts Scaling factor: HiDPI(2x)

Amigo, prueba esto, recuerda cambiar la ruta (path) En mi caso esta en /opt/firefox-dev
Importante: StartupWMClass=firefox-aurora

@oraimagini Maybe check file permission

Whenever I launched Firefox Developer Edition in Wayland session of Gnome, there were two icons in my dash. It took me some time to find the answer.

It turns out Firefox Developer Edition has a different wmclass value depending on the session type.
In x11 wmclass is firefoxdeveloperedition, in Wayland it is firefox-aurora. The StartupWMClass of the .desktop has to be edited accordingly.

P.S. To find out wmclass value, you can use xprop WM_CLASS in x11, and looking glass command in wayland (press alt+f2, then type lg, press enter, and go to windows tab).

This guide is terrible.

Version of the shortcut with the icons and quick actions fixed as of 2022.

⚠️ In the options Icon and Exec (3 times), replace firefox-dev with the name of the folder you gave when creating the program folder (step 5, you should have firefox if followed this tutorial)

/usr/share/applications/FirefoxDeveloperEdition.desktop

@mauriciabad Why NoDisplay=true?

Can somebody tell me why someone says you should create "/usr/share/applications" and some other people say "~/.local/share/applications"
What is the difference between those?

Thanks for this!

This works for me in ubuntu
my firefox dev location is in /opt/firefoxDeveloperEdition, the desktop file is in /usr/share/applications/firefoxDeveloperEdition.desktop
