Sometimes Firefox uses excessive amounts of CPU as reported by Windows Task Manager or by the top command on Linux.

Excessive CPU on certain web sites

If Firefox uses lots of CPU on certain web pages, please report the problem using Help -> Report Broken Web Site. Usually there's executable code on the site that is consuming the CPU. On the other hand, if a bug in Firefox is causing the excessive CPU usage, this will help track down the problem.

The Flashblock extension can help the problem by blocking Flash code that consumes excessive amounts of CPU.[1][2]
