The Code to Check: if(window.getComputedStyle(document.getElementById("check"),null).getPropertyValue("display") == "inline") And the CSS for this: div.history a { display: none;} div.history a:visited { display: inline;} Later I saw that it should already be fixed but it isn´t. Reproducible: Always Steps to Reproduce: 1. Visit a site 2. enter the site adress in the textbox at the included site 3. Click Check and see what happen Actual Results: It says weather a site was visited or not. Expected Results: There shouldn´t be an ability of checking this with javascript. I read, that this is already solved but with my code (I don´t know what i did different) it´s working in my firefox.
