Firefox Makes X take the full CPU

[Stack]

The original problem was certain pages would cause the Xorg process to take 100% of the CPU. These pages were
http://live.gnome.org/Luminocity and http://cvs.apache.org/dist/ant/v1.6.3beta1. I could move the mouse and
that was it. Nothing else was responsive, nothing moved, etc...

I removed the .mozilla directory from my home directory and was able to visit these pages, no problem. Then, I
went to http://live.gnome.org/Luminocity and resized the firefox window, which then gave the previously
described problems.

To fix the problem when there is a lock like this, I have to kill the Xorg process and then restart gdm.

The only other thing that may be related is that the following line shows up in dmesg once the freeze happens:

NVRM: Xid: 13, 0000 02005600 00001796 00000100 00000000 00000080

The card I have is a GeForce 440 Go with 64MB of RAM. I am using the accelerated nvidia driver provided by
Ubuntu. I do have RenderAccel set to "1".

Note: I am not running luminocity at all, so that is not the problem.

I am using the latest Hoary as of Thursday, April 7th, 21:48 EST.
