Enables visited link colors on every website for convinient browsing it uses the color from the firefox options , look at the pics for explanation naturally, human vision detects dark red colors the best without it being annoying, bright red is distracting as is bright greens. i use #990000 on pc and on android #992020 (becasue the phone´s screen is darker ) have fun :) edit: on android there are no color options , you need to go to about:config and there edit you color manually look at the last image for explanation.. you can do this on desktop too if you want a special color.
