I am working on an updated version of Firefox (47.0.1). Till the last week it was working fine. But from today it is showing "Your connection is not secure" message. It is also not loading the css. Always showing Error with "Slack" application and Slack is beautifully working on Google Chrome.

Always i would like to work with Mozilla Firefox.

Check out why the site is untrusted and click the "Advanced" button to expand this section to see extra details. If the certificate is not trusted because no issuer chain was provided (sec_error_unknown_issuer) then see if you can install this intermediate certificate from another source. Click the "Add Exception" button to inspect the certificate in the Certificate Viewer.

If you can't inspect the certificate via "Add Exception" then try this:

Open the "Add Security Exception" window by pasting this chrome URL in the Firefox location/address bar and check the certificate:

  • chrome://pippki/content/exceptionDialog.xul

In the location field of this window type or paste the URL of the website with the https:// protocol prefix (https://xxx.xxx).

  • retrieve the certificate via the "Get certificate" button
  • click the "View..." button to inspect the certificate in the Certificate Viewer

You can inspect details like the issuer and the certificate chain in the Details tab of the Certificate Viewer. Check who is the issuer of the certificate. If necessary then please attach a screenshot that shows the Certificate Viewer with the issuer.
