With color perception limited vision, I cannot distinguish default colors for visited/not-visited link colors. I tried changing colors in Settings via: Colors / Override FF's default colors for text, website backgrounds, and links: I changed the colors to what suits my needs BUT just changing those colors ALSO put focus(?) lines around various texts and randomly changes colors elsewhere in arbitrary fashion making my changes unacceptable. What am I doing wrong? I am not stupid, but I do not understand the langauge used in describing "modifications." It would be useful for people in similar states of lack of knowledge to have at least maps/legends of web pages explaining the arcane language of webs. TIA Stephen
