Yes, that was about styling active links, not visited links - and about outline around clicked links. However, now as I see it the situation becomes more difficult because browser developers seem to abandon this useful feature. When I use 'Open link in new tab' Gecko browsers have always put a dotted outline around clicked links and set them to the :active style so that when I went back from the new tab to the original one, the clicked link was still in the outline and was styled like an active link (for example red) - so it stood out easily. In Firefox 8 they got rid of the outlines - they appear only after I click a link AND come back using the back button. And still this doesn't happen always. When opening in new tab, there is no outline at all and the active style is applied only for a short time so it's no longer there after a while. Among other browsers only IE applies active styles long enough to be useful and uses outlines.
I don't know why but sometimes I feel like the web technology is going backwards and usability is thrown out the window: browsers removing outlines and active styles, getting rid of status bars (Firefox, IE, Chrome), removing location bar drop-down history (Opera), removing hourglass cursor while page is loading (Firefox), removing application menus by default (FF, Opera, IE), messing with UI and placing reload and stop buttons in some obscure locations, web sites suppressing all things that make web pages usable (styling of vbulleting 4 forums), removing all kinds of useful options and settings aka "dumbing down" (Firefox), removing "http://" from address bar (Firefox), and the list goes on and on... Does this mean I am not able to adapt to changes? I just can't understand why people have to mess with things that work and are useful... Sorry for the little off topic!
