GOOGLE CHROME FIXES BROWSER HISTORY LEAKS BY PURPLE “VISITED” LINKS

Summary from the TLDR InfoSec newsletter

Historically, bad actors have been able to track users' browsing history by utilizing the ":visited" CSS selector, which turns links purple. Google is aiming to address this leak by changing the way that the ":visited" selector is applied to only display if the user has visited the site from the current top-level site and frame origin. Effectively, the browser will now display purple links based on the combination of the current site and visited sites.
