Long story short, I'm working on a particular website that has dark purple for unvisited links, light purple for visited links. Yes, I know, not the best color scheme. Anyone who knows links can guess where this is going. I thought I had styled some links appropriately where it turned out I hadn't. Now, I can't be sure which links are appropriately styled and which aren't. Web Developer saves me once again from having to clear the history by offering in the Micellaneous menu a way to make all visited links unvisited.
Thank you, Web Developer, for making my browser and browsing experience under my control, not that of someone else's decisions or mistakes.
