Public bug reported:
Occurred whilst using Firefox Nightly 59.0a1 (2017-11-22) - session had
been active for several days. No crash report or other useful info in
other logs than shown here.
Firefox stopped responding then I realised the entire desktop had
likewise although touchpad/mouse movement was fine. Keyboard input was
also unavailable (including Ctrl+Alt+Fx).
SSHed in and after seeing the entries in kern.log did "pkill firefox"
upon which full control was regained.
