If I go to System Settings -> Applications -> Default Applications -> Web Browser and select "in the following browser" and type "firefox", konsole works as expected. If I then change it back to "in an application based on the contents of the URL", it breaks again. I expect this is some broader KDE issue rather than something relevant to konsole, but I don't know how to test further.
