When I right click on Firefox in the dock and select close all, then restore my Firefox session, it doesn’t bring back all the closed windows, just one. When I force quit Firefox then restore a session I get all of them back. So KDE closes each window individually rather than quitting or killing the whole app, which is disruptive for me.
Any ideas or solutions other than using hotkeys to quit apps? Ideally I want to right click on an app and select a quit option to kill the app.
