With today's Firefox nightly build I see a peak of 337MB with it. Image discarding has improved recently.

I doubt that the patch helps in this particular case as all images are present in the DOM, so Firefox will merrily load all of the images, independent of whether they are visible or not. This has been a longstanding architectural problem.
