Script Summary: Marks Visited Links AND Images for easy recognition.
Its purpose is to mark the visited links and images in a web page for easy recognition. With so many (maybe hundreds) links in a single page you need a way to track and easily identify the links you already visited, especially if the web page resembles a list.
I know there are dedicated add-ons like stylish specialized in that area but there are at least 2 drawbacks. First, in Stylish you can't easily add/remove the sites that you want (as a user) the style to apply. Second, why have a 2nd add-on for something Greasemonkey (an add-on with other uses) can easily handle.
The script has 4 "functions" for the time being:
1. Makes the unvisited links bold (keeps the original color)
2. Makes the visited links dark red with a line-through
3. Adds a simple hover effect with soft yellow background and bold letters for all links (useful if you can't easily read some of the line-through visited links)
4. Adds a dotted red border to the visited thumbnails or image links.
As I said you can easily assign it to whatever sites you feel like through the greasemonkey interface.
Update for Firefox 7.01: It seems to be a bug concerning the text decoration line-through I use for the visited links. https://bugzilla.mozilla.org/show_bug.cgi?id=645786 It wasn't present in 3.6 versions, but after I updated to 7.01 it came up. I try some differnt syntaxes but I didn't manage to overcome it. Also somethink seems to broke with the styling of the images. When I found I fix I will post it here.PEACE!
UPDATE: It's not a bug it's a ...feature! Firefox's guys have disabled the changing of a:visited because a secutity risk/exploit concerning css style.
Added the option to enable/disable the highlighting of images. To do that use the "User Script Commands" (right-click the monkeyface on your status bar) and select Visited Images ON/OFF accordingly. Your choice is saved through sessions.
The hovering effect has a background color that derives from a semi-transparent color. (You must use a browser that supports CSS3 Cascading Style Sheets)
In the previous version hovering over an image which has an overlay link caused the image to complete or partially hide behind the yellow color of the hovering effect.
Now you get a semi-transparent color that doesn't block the image.
