How to install StopTheMadness in Chrome and Chromium browsers

The StopTheMadness browser extension is bundled inside the Mac app. You only need to enable the extension once in your browser, and then it will automatically update along with the Mac App Store app.

The instructions below are for Google Chrome. You would follow similar steps to enable StopTheMadness in another Chromium browser such as Brave, Microsoft Edge, Opera, or Vivaldi. The user interface in other browsers may look slightly different, but otherwise the process is the same.

  1. Open Google Chrome.

  2. In Chrome, open the "Window" menu in the main menu bar and select "Extensions" from the menu.

  3. In the Extensions window, enable "Developer mode" in the upper right corner.

  4. Open the StopTheMadness app.

  5. In the StopTheMadness app, select "Chrome or Chromium browsers…" under "Install in other web browsers".

  6. Drag the StopTheMadness icon out of the "Install in Google Chrome or Chromium Browsers" window and into Chrome.

  8. StopTheMadness is now installed in Google Chrome. You can change the website options by selecting "Details" and then "Extension options", or by simply clicking the StopTheMadness icon in the toolbar. See Google Chrome Support for more information.

If you wish, you can disable "Developer mode" after installing StopTheMadness. The extension will continue to function and receive software updates.

If you see an Errors button, don't worry, this is actually just a warning about the deprecated Chrome extension manifest version 2. StopTheMadness continues to work, and it will adopt the newer Chrome extension manifest version 3 before the deadline.
