It's working for me as well using the latest update to Safari and macOS 10.12.6. By the way, I never even knew you could use the delete key to jump to the previous page. Thanks for the tip.Color change for visited links is working for me with Safari 12.1 in macOS 10.12.6 on the MacInTouch home page (where they turn from blue to purple after being clicked). But behavior is like you describe - not changing color - on these MiT Community pages. I'm not sure what the difference is, but the MacInTouch Home Page is simple, static HTML.
