Some websites just can’t take “no” for an answer. Instead of respecting visitors’ choice to block third-party cookies—the identifiers that track browsing activity as a user moves from site to site—they find sneaky ways to bypass those settings. Now, makers of the Brave browser are taking action.

Earlier this week, Brave Nightly—the testing and development version of the browser—rolled out a feature that’s designed to prevent what’s known as bounce tracking. The new feature, known as unlinkable bouncing, will roll out for general release in Brave version 1.37 slated for March 29.

Overriding privacy

Bounce tracking is one of the key ways websites circumvent third-party cookie blocking. When a browser prevents a website such as site.example from loading a third-party tracking cookie from a domain such as tracker.example, site.example pulls a fast one. When site.example detects that the tracker.example cookie can’t be set, it instead redirects the browser to the tracker.example site, sets a cookie from that domain, and then redirects back to the original page or a new destination.
