There is no reference to firefox anywhere in Konsole code or desktop files. If there is on your system, then try with a freshly created user account. If the issue persists there, report it to the bug tracker of your distribution.
Reopening with some additional info. I found it's not a strictly Firefox thing. It actually seems to track based on an icon set in a .desktop file. In my case, I usually run Firefox in a Konsole window by launching a .desktop file. But you can do the same thing with other programs. Consider the following desktop file: #!/usr/bin/env xdg-open [Desktop Entry] Comment[en_US]= Comment= Exec=gimp GenericName[en_US]= GenericName= Icon=/usr/share/pixmaps/chromium-browser.png MimeType= Path= StartupNotify=true Terminal=true TerminalOptions=\s--noclose Type=Application X-DBUS-ServiceName= X-DBUS-StartupType= X-KDE-SubstituteUID=false X-KDE-Username= As you can see, it will launch gimp in a terminal window, but the .desktop's icon is set to chromium-browser.png. When I launch this, the chromium icon is what will show up in the menu for Help : About Konsole. Additionally, once that is open/running, any further Konsole windows I open will show the same thing, even though they were started normally, and even if the original window has been closed, as long as there has always been a Konsole window open since the original one.
I would suggest asking on your distro's site.
