High CpU usage with Firefox, I have pictures!!

Ok please see the attached screen snap of what Comodo is blocking, can anyone tell me if this is normal.

Also Firefox has locked up, this happened with a 100% Cpu usage, but suddenly drops as soon as task manager is opened so I cant tell you for sure which program is doing it.

I am in the same session now and using SeaMonkey to acces the forum here.

Any ideas??
