I HAD Firefox on my laptop and it was working fine. Had some problems with my ISP but thought it was my laptop so made the mistake of uninstalling Firefox. Got my ISP back up and re-installed Firefox but now can't connect to my Firefox account because it says I'm NOT connected to the Internet - gives me a Secure Connection Failed error. I need to sync my laptop to my PC, phone and tablet but can't even login to do so. I'm using a Windows 10 system on my laptop. I KNOW I'm connected to the Internet because the Edge browser on my laptop works fine.

You can click the "Advanced" button on the Error page in case this button is present to expand this section and show extra details. If the certificate is not trusted because no issuer chain was provided (SEC_ERROR_UNKNOWN_ISSUER) then click the blue error message to expand this section and show the certificate chain. Please click "Copy text to clipboard" and paste this base64 encoded certificate chain text in a reply. That will allow us to check details like the issuer of the certificate.
