How to uninstall List Goal extension (Chrome)
Open Chrome.
Navigate to "chrome://extensions."
Scroll down until you find List Goal.
To merely disable, uncheck the Enabled button. (This keeps the extension on the user's computer, but makes it inactive.)
To delete the extension, click the trash can icon to the right.
Once you select the desired option, you can close the "chrome://extensions" tab.
That's it.
