IMHO it was the restart that "fixed" it. I experience this "getting slow"
think to happen for a long time. After several days of run, firefox needs
to be restarted. 1. it's taking too much RAM, 2. usually causing higher
CPU load than after restart with same tabs and history open. BTW: same I
have to do with gnome-shell, so maybe some graphics card driver is
leaking.
