I have a really hard time with motion--my brain is unable to block it. I've become very frustrated with, for example, news sites that instad of text and still images, have started showing animated clips or short videos. I've tried a firefox extension that is supposed to stop everything, but it doesn't work terribly well. I use "reader view" extensively, but it doesn't always work.

(Incidentally, I have the same issue in real life when I go to a restaurant with a TV, so I intentially sit with my back to the TV.)
