I am also having the same problem since I had upgraded to the latest Firefox release. It is not related to any specific URL or a type of web page. It occurs even if I have just Firefox running and no other application.
I am on a 32 bit architecture with 2.6.24-21-generic kernel and running Ubuntu 8.04.1.
