Comment 148 for bug 38131

I can confirm this in the recent release of Firefox 4. As Steve mentioned, it's easily reproducible simply by performing a Google Image search. This causes high CPU usage from the X server and on my computer at least, the display temporarily freezes.

I'm running Arch Linux, with an Nvidia 8200M (notebook) video card. If I can help by providing more information, please just ask. This has basically made Firefox unusable for me (so I'm posting from Chromium).
