StopTheMadness for Microsoft Edge is bundled inside the Mac app. You only need to enable the extension once in Edge, and then it will automatically update along with the Mac App Store app.
Open Microsoft Edge.
Open the "Microsoft Edge" menu in the main menu bar and select "Microsoft Edge Extensions" from the menu.
In the Extensions window, enable "Developer mode" in the lower left corner.
Open the StopTheMadness app.
In the StopTheMadness app, select "Install Microsoft Edge Extension…".
Drag the StopTheMadness icon out of the "Install in Microsoft Edge" window and into Edge.
Drop the StopTheMadness icon into the Edge Extensions window.
StopTheMadness is now installed in Microsoft Edge. You can change the website options by selecting "Details" and then "Extension options", or by simply clicking the StopTheMadness icon in the toolbar. See Microsoft Edge 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.
