When I go to some companies websites and do a job search in their career section and the search returns a listing of jobs on a page that is encrypted and I click on a link by a job title that opens a page with the job description on it and I then return to the original page with the job listing using a return link that is provided on the page so the search will not expire if I use the back button the link I initially clicked on by the job title is not changed from blue to purple so that my place will be marked and I will know not to duplicate my efforts by clicking on the link again. Firefox does change its visited links color on regular none encrypted pages. From what I gather Firefox relies on cookies being downloaded into it cache for it to be able to change the color of visited links and this design goes back all the way back to the earliest versions of Netscape. Some secure website and pages that are encrypted do not generate cookies. I assume this is why the visited links did not change. When I go to similar sites or pages using Internet Explorer they do change leading me to believe Internet Explorer has another way of keeping up with visited links. Does anyone know how Internet Explorer does that and why Firefox doesn't?
