On the next screen turn off the Toggle button to disable the extension. You can again revisit the page to enable the extension back.
OR
1. Go to Extensions from your chrome browser by clicking on 3 dots on top right corner.
2. Once you are on the page, find Mr. E tool and click on toggle switch which will disable the extension.
