Thanks for the report, I was able to reproduce the issue.

Note:

1. The issue is not reproducible on Chrome and Microsoft Edge.
2. Connection is not secure on Firefox but secure on Chrome.

According to SSL Labs:

Tested with: Browser / Version: Firefox Nightly 78.0a1 (2020-05-11) Operating System: Windows 10 Pro

Moving to Needsdiagnosis for further investigation.

Looks like classdojo.com domain was removed from Firefox HSTS preload list https://hg.mozilla.org/integration/autoland/rev/85fd9ac6ca7905cf6cc0ed0dd824a28d28fe504a, so auto redirect from http to https is not happening in Nightly

According to Chrome's list https://hstspreload.org/?domain=classdojo.com
"classdojo.com is currently preloaded, but no longer meets the requirements. It may be at risk of removal."

I'll move this to needscontact, since the site should fix this to match the requirements

It's accessible through https: https://www.classdojo.com/ or http://www.classdojo.com (in case if www is present, the redirect is happening )
