** Major trust issue alert ** The add-on reports that it now has a compromised back end service API. You may now see an error "This public key does not match the one required by the server" within the add-on about:addons config screen. I have tried this on multiple computers, same catastrophic security error. The public key no longer matches the expected API key. This add-on normally sends all your website URLs to a back end server that the developer hosts free of charge (how "generous"... hmmm). Notwithstanding this suspicious setup which is funded "some how", this error would indicate their server has been compromised. Someone else is now hoovering up all your URLs, maybe the CIA, FBI, MI5, Mossad... who knows.
Also, https://www.ssllabs.com/ssltest/analyze.html?d=checkmyhttps.net suggests the server's certificate chain is incomplete. which is odd.
The Public key you should see in the add-on..
