NB: My question is essentially identical to this, but it was recommended I open a new question as the given solution doesn't work.

Basically, I have Firefox Develop Edition installed. I managed to add the icon to the dock, and changed the icon to be correct. As such, I am 100% certain this is the correct .desktop file to be editing.

This is my firefox-developer.desktop file:

[Desktop Entry]
Version=1.0
Type=Application
Name=Firefox Developer Edition
Icon=/home/jhpratt/.local/share/umake/web/firefox-dev/browser/chrome/icons/default/default128.png
Exec=/home/jhpratt/.local/share/umake/web/firefox-dev/firefox %u
Comment=Firefox Aurora with Developer tools
Categories=Development;IDE;
Terminal=false
StartupWMClass=Firefox Developer Edition

The final line of this is what the recommended solution in the post above is. Running xprop WM_CLASS and clicking on the Firefox window returns WM_CLASS(STRING) = "Navigator", "Firefox Developer Edition". I have tried setting StartupWMClass to Navigator, Firefox Developer Edition, and Navigator, Firefox Developer Edition, none of which have worked. I restarted my session in between.

Update: It does not work in a Wayland session, but works as expected in Xorg.

  • Are you in a Wayland session? What happens if you switch to an Xorg session? – pomsky Apr 11 '18 at 01:15
  • It does not work in a Wayland session, but works as expected in Xorg. I was under the impression that Xorg is the older, less favored, of the two, however. – jhpratt Apr 11 '18 at 01:19

    Wayland is certainly more secure than Xorg, but I'm not sure about the "less favored" part though. Many feel Wayland is not ready yet to completely replace X. In fact Ubuntu developers have decided to ship the next LTS release (18.04) with X as default instead of Wayland. – pomsky Apr 11 '18 at 01:24

    Software requirements state that X.Org 1.0 or higher (1.7 or higher is recommended) is required. See https://www.mozilla.org/en-US/firefox/58.0.2/system-requirements/ – Terrance Apr 11 '18 at 01:39
  • @Terrance That doesn't make much sense, cause I was still running FF under Wayland. It's just the icon. – jhpratt Apr 11 '18 at 01:41

    @jhpratt you were probably running FF in XWayland in Wayland, not in Wayland directly. – muru Apr 11 '18 at 01:43
