Thanks a lot bro!!!
Only one note: "StartupWMClass=Navigator" worked for me to avoid duplicated icon on dock
I have Ubuntu 22.04
For some reason it didn't help. I had to set it to
StartupWMClass=firefox-auroraon my Ubuntu 22.04.1.This issue is likely related to the .desktop file of your Firefox Developer Edition. Specifically, the StartupWMClass property in the .desktop file may not be set correctly. The StartupWMClass property helps the GNOME Shell to associate the running application instance with the correct .desktop file and, consequently, the right icon in the dock.
To fix the issue, follow these steps:
1)Open the Firefox Developer Edition and then open a terminal.
2)In the terminal, run the following command to get the WM_CLASS property of the Firefox Developer Edition:
xprop WM_CLASS
After running the command, your cursor will turn into a crosshair. Click on the Firefox Developer Edition window. The terminal will display the WM_CLASS value, which should look something like this:
WM_CLASS(STRING) = "firefox", "Firefox Developer Edition"
Take note of the second value (in this example, "Firefox Developer Edition").
3) Open the .desktop file for Firefox Developer Edition with a text editor. The file should be located in ~/.local/share/applications/ and named firefox_dev.desktop. If you can't find it there, look for it in /usr/share/applications/.
nano ~/.local/share/applications/firefox_dev.desktop
4) In the .desktop file, find the StartupWMClass line and update its value to match the second WM_CLASS value you found in step 2. In this example, the updated line should look like this:
StartupWMClass=Firefox Developer Edition
5) Save the changes to the .desktop file and close the text editor.
6) Restart your Firefox Developer Edition, and the issue should be resolved. The new instance should now be associated with the existing icon in the dock.
Brother you have any idea how to uninstall that?
I think u can just delete the firefox..bz2 file in opt folder

chownthe directory in/opt/Thanks!

How to remove? I cannot remove and it's annoying. I tried to remove with purge and autoremove but it removed the standard firefox... I also tried names like firefox-dev etc and none of them worked...
Someone said you can just delete the fierfox.bz2 file in /opt directory but idk
Thanks it worked for me on Ubuntu 22!
Just one question does it update automatically as well?

Any idea on how to have both regular firefox and firefox dev installed at the same time? I had the regular installed before doing this and it just got installed over the old one
You can't use "Add to Favorites" action on Ubuntu 22.04 with this config.
StartupWMClassshould be without spaces to fix it. So, I usedStartupWMClass=firefox-developer-edition.Thank you, work beautifully in openSUSE.
I put it in my home folder instead (doesn't require root)
Then I begin at step 10 to register the app.
Thanks a lot, i was using chrome all alone but i don't like it anymore
Its work! Thanks!
Thanks, I'm a beginner and was surprised that it worked for the first try
Thank you so much, what if in future how can i update the firefox developer edition.
