Firefox 3 CPU usage high

post #1 of 5
Thread Starter 
Is it just me but the CPU usage in FF3 is really high when you visit any site?CPU usage spikes to 100% (monopolizes one of the cores of my dual core CPU) for 30secs to 2 mins. This happens at random times, unrelated to active browsing. I've disabled all my addons with no effect.

I might of solved the problem. The problem was the Nvidia Drivers that were causing laggness. I switched back to 175.19 drivers and its fine now. I was using the 177.41 driver with Physx drivers before thats why.

It could be Flash. Since it's a closed codec, it's hard to determine what it does - specially on 64bit. Another possibility is extensions, sometimes poorly written extensions cause havoc also.
