When I go to a site with a dark background and white text, and text looks blurry and discolored, giving it that red and green around the edges look. When I highlight a part of the text, all the text on that particular line then becomes slightly bolder and looks correct. I checked to make sure it wasn't the NoSquint addon causing this, and it wasn't. It still did it when I disabled it. I have cleartype enabled. Here is a link to a screenshot of my problem. http://home.comcast.net/~psypark/Image5.jpg
That could be your moniter, I know my hdtv is like that. check cable connections, resolution, and video card.
