Why does firefox use so much cpu how to#

I'm using the latest Firefox Beta 20.0 on OSX Mountain Lion 10.8.2, and my version of Shockwave Flash is 11.6.602.167. Checking the Task Manager found that Firefox was eating a lot of memory.

I thought this is unnatural, especially because from what I've read about NPAPI, NP_Initialize is meant to be called by the browser only once. I've tried investigating through CPU sampling using Xcode's Instruments.app, and what I've found odd by walking down the sampled call stack is that about 80% of the CPU usage seemed fishy, and was due to exactly 4 recursive calls for NP_Initialize (see picture for one of the 2 call sites where this happened).Д«oth sites where this is happening (and not much else?) are inside the stack tree of 0x10fb8ec66 > 0x10fb93947 (in this sample). for every tab that the browser opens, while Firefox uses a single process for all tabs. That worked fine for a while, but at some point playback started skipping so I decided to investigate. Note that if a process allocates and frees memory very quickly. Like many people before myself, I'm having problems with Flash bringing down an entire CPU core (specifically, one of the threads is always using up 100% CPU).ДЇlash is probably running on more than 1 page (I'm using a lot of tabs), but what seemed to start this CPU usage was a bit after I started streaming a movie. If you receive frequent alerts from a particular component, and notice degraded computer performance, identify the component and take necessary action.
