FireFox add-on, Color That Site. Still playing around, but no more invisible blue lines. Changed background and foreground colours.
If you've read any of my dissertations on the subject in other threads on this site, you might recall I know they are there because I THINK I can see them when I look away...out of the corner of my eye. Yet when I look straight on...well, depends on angle, time of day, phase of the moon....... This new fix does away with all of that, so I can work it.
