visited link enabler автор ulf3000

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.
