I'll just add that on the Ubuntu 18 LTS system at which I'm currently looking, the file is here: /usr/share/applications/firefox.desktop Mine has two Actions - the second one being - open a private window. I could see where I might easily add additional Action items, except that I would personally not be able to supply the Name attribute for the many locales I'm seeing in my file. When I right click the icon on the dock, I see the two Action items mentioned, and I'm assuming a third would show the same way.

KDE:  right-click on the application menu, "Edit Applications", Internet->Mozilla Firefox, edit the Command: entry so that it executes what you want instead of the default "firefox %u" command. Everything:  Just find whatever .desktop file is being used by your desktop environment with "locate \*desktop | grep firefox" (there may be a few of them.)  Then edit the Exec= line so that it invokes the command line you want instead of the default "firefox %u".  This will almost certainly break every time firefox gets updated though. Alternatively, copy the default .desktop file to wherever your Desktop directory is, then edit that, and always launch your firefox from that icon/whatever instead of the system menu.  That will get rid of the "menu entry goes back to default after update" problem. -- Crow202 Blog: http://crow202.org/wordpress There is no Darkness in Eternity But only Light too dim for us to see. --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org To subscribe, unsubscribe, or to change your mail settings: https://lists.phxlinux.org/mailman/listinfo/plug-discuss --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.phxlinux.org To subscribe, unsubscribe, or to change your mail settings: https://lists.phxlinux.org/mailman/listinfo/plug-discuss
