hi, i don't think it is possible to give a general answer in this case. what is the site in question and what's the exact error message/error code that you are getting in firefox?

The website in question is Happy Gymnastics (www.happygymnastics.com)

The message says, "Your connection is not secure. The owner of www.happygymnastics.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website."

To verify on your end, do this:

1. Open Firefox and search for "happy gymnastics" 2. Click on the first search result 3. Verify you get the same error I do.

The problem is that when you follow the three steps I've outlined, Firefox redirects to "https" instead of "http." It's like it won't re-index the new url.

Thanks

hi, i cannot reproduce the issue and land on a http-version of your site on firefox as well. it may be that if a particular firefox version has come across a secure version of your site in the past, it is then upgrading to https by default - this could be the case if your site has served a hsts-header in the past. if you want to work around that i think the only way is to provide a working https configuration of the site - certificate authorities like letsencrypt.org will also provide certs free of charge...
