Adblock of various types and versions in FF and Chromium helps gets rid of the most distracting page elements (animated or flashing ads), but it's never perfect, so I sometimes resort to zooming in and scrolling the ad off the page, or moving the browser window to take that portion off the screen. I don't have a visual disability, but functional zoom buttons are very important for me, and any website that breaks or disables them is one I'll likely avoid. This is a big issue with many "mobile" websites that for some reason seem to think locking down the size is somehow a good idea. How do they even accomplish this feat of stupidity, technically?
