Bug Description
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.
