Specification

Summary

We intend to prototype browser changes to mitigate bounce tracking on the web. We do not have a final design yet, but this will likely involve deleting storage from sites that appear to be bounce trackers when users have blocked third-party cookies. See the explainer for more details.

Internals>Network>Cookies

Motivation

Redirects can be used to implement cross-site tracking of users. In addition, redirects can be used to simulate third-party cookies even when the user has chosen to block third-party cookies. The primary goal of this effort is to mitigate these privacy issues.
