I uninstalled all extensions to narrow it down to firefox, and each time I visit a page that isn't cached, the CPU spikes to 100% and my system becomes really slow. This wasn't a problem with the previous version of firefix that I had. Reproducible: Always Steps to Reproduce: 1. Visit uncached pages 2. 3. Actual Results: CPU usage spikes to 100% and firefix becomes unresponsive. Expected Results: CPU usage stays at normal level and page loads smoothly. No errors were reported. I want my old firefox version back!
Does this also happen in 1.5beta? Does this happen with default settings too (tried a new Firefox profile?) What pages this happens on?

Hi, Yes. I downloaded the recent 1.5 b2 version and had this problem. I'll attach a screenshot of perfmon as I started up firefox and visited: http://www.google.com/ig http://www.cnnsi.com http://www.cnn.com I've also observed this with other generic sites like yahoo.com and microsoft.com.
