Should your browser crash over this? This bug is described in detail here
If your browser doesn't crash right away, you have two options. One is to wait, and just scroll up and down and such. The second is to resize the window so that it is really small, and then grow the window. This normally does the trick.
For some reason or another, it will sometimes crash immediatly, and sometiems it will wait for a while.
