Hi!
When I launch firefox it shows in the taskbar with the icon of VLC player.
Firefox icon is OK both in the desktop and in the menus
Why?
regards
I forgot to say: Opensuse Leap 42.2. Plasma 5.8.
It seems I have found the solution.
firefox and thunderbird are GTK applications, so its icons and configuration are dfined at system settings->Application style->Gnome application style (GTK), so they are gnome related.
So i force reinstallation with yast of all icons packages and most of gnome packages and now it seems to work fine.
regards
I think I found the error
In ~/.local/share/applications I have a lot of .desktop files with the icons of the applications.
In the case of firefox, i have a file firefox.desktop with this content
[Desktop Entry]
Exec=/home/fernando/Desktop/Firefox
Icon=/usr/share/pixmaps/vlc.png
Name=Firefox
Type=Application
I don’t know why this “/usr/share/pixmaps/vlc.png” I didn’t put it there, but it seems that task manager use sometimes this icon and othr times other icon from another place.
Changing to
[Desktop Entry]
Exec=firefox
Icon=firefox
Name=Firefox
Type=Application
solved the problem
