Public bug reported:
Firefox is slow to respond and showing >100% CPU In top/atop since the
update to 42. Can be reproduced on two machines, an Acer Revo RL80 with
dual core Celeron 1.50Ghz, and an Asus S400CA laptop with quad cord i7
at 1.90Ghz. The Revo is running 15.10 and the Asus 15.04, currently
being upgraded. Both were working fine until the last couple of days.
