The Axel Springer Blocker (ASB) - Redux Edition is a free Chrome add-on developed by Revengeday. This browser extension allows users to block nearly all websites associated with the Axel Springer publishing company. With the 2019 update, ASB offers an updated blocklist, removing city portals (optional) and fixing bugs for the latest Chrome version on macOS Mojave.

The ASB - Redux Edition includes a changelog, showcasing the updates made to the extension over time. Updates include the addition of the "Redux Edition," design adjustments, bug fixes for the latest Chrome version, and the removal of websites that are no longer associated with Axel Springer. The developer also humorously mentions receiving a cease and desist letter from Axel Springer.

For those interested, the source code of ASB - Redux Edition can be found on GitHub.
