Yes that's the conclusion I had drawn, whereas an explicit 'kill' by user
chooses the Quit function and firefox remembers the open tabs and windows
(not kill -9).
I mentioned previously that I had recently switched back to starting X from
level 3, instead of going via level 5 (i.e. now avoiding using graphical
login and xdm/gdm or whatever).
I *think* my previously reported problems of keyboard input focus not
always following the mouse have disappeared as a result. I have only been
using the new startup procedure for a few days (on both laptop and desktop
machines), so I can't yet be sure. As everything seems to be working ok
without the previously mentioned xorg-x11-xinit-session package, I have
not tried using it.
Another (not window manager related) problem:
My laptop was upgraded from Fedora 22 to 24 yesterday. I then found ssh
login without password from other local machines no longer worked.
After about two hours of wasted effort I eventually discovered that the
defaults had changed.
In case anyone else has this problem I found the answer here:
For this specific error, you need to add "PubkeyAcceptedKeyTypes=+ssh-dss"
(without the quotations) to the bottom of your /etc/ssh/sshd_config file.
