I use last firefox (32) on MacOS X 10.6.8. Sometime firefox start using 100% a one CPU, from that time the only way to stop it was to quit (it take severals seconds, sometime it hang). When it start i can close all windows, firefox continue using 100% CPU.

I follow standard instructions (update to lastest, disable plugins and extensions...) it do not work.

I not a configuration to reproduce the problem : keep iCloud mail open in one tab is the way to reproduce the problem sometime after a few minutes, sometime after some hours : but it also happend sometime with no iCloud open...
