Add-on does not login to any gmail accounts! Rated 1 out of 5 stars

This add on does not does any of its stated features at all and does not log in to any given gmail account.
Please repair or fix it or remove it from the add-on directory.
Also I've realized that many users reported this login error issue so many times before mine now and still no response.
DO NOT DOWNLOAD OR USE BECAUSE IT DOES NOT LOGIN.
