@ roman-averin Do you know if the crashing is a regression in this particular update or was it crashing with previous tracker-miners versions as well?
Not that this update is already in stable update so giving karma here doesn't affect it at all any more. Would be good if you could file a ticket with more details.
gnome-shell carries a list of desktop files it shows in the launcher. Looks like the name changed in https://src.fedoraproject.org/rpms/firefox/c/36a09da5bc1a14f6af3fe163c84f9852e23c44c8?branch=rawhide so it should be just the matter of updating https://src.fedoraproject.org/rpms/gnome-shell/blob/rawhide/f/gnome-shell-favourite-apps-firefox.patch with the new name.
I'm in general in favour of the new org.mozilla.firefox.desktop name - it brings us closer to upstream packaging, however I am not sure it's wise to change it in stable Fedora releases. F39 and rawhide should be fine at this point, provided that we update the name in gnome-shell of course.
