Toggle between designed colors and generic colors Rated 5 out of 5 stars

So good, a must have on your browser. I have bad eye sight and is very sensitive to light, many sites are design with white background making it very difficult for me to read anything. With this baby I can switch the background off and use a grey background that I setup as a generic color for all sites.
