I always browse by using the Firefox function to change display colours, usually to light green on dark green. I'd prefer green on black, but it gets annoying because so many input boxes on web-sites have black text as default, which is then displayed on a black background. Green on black was the default on the first computer I used, and apart from giving me a nostalgic tingle, I find it easiest on the eyes. The only thing that I can see that really doesn't work is that it also affects images (presumably those enclosed in colour tags? no idea why), so sometimes I have to switch over to default colours (increasingly rarely, though, it seems).
