Firefox browser shows the SSL Certificate on my businesses website as "not secure."

I recently updated the SSL certificate for my business. My Firefox browser indicates the certificate is "not secure." When I navigate to my website using Bing, the SSL certificate shows as being "secure." I'd like the SSL certificate to indicate it is secure using Firefox browsers. Is there something I can do so that when someone lands on my website using Firefox it will correctly show that it is a "secure" site?

Thank you.

Update: with the passage of 24 hours, the "not secure" warning is no longer present when I open my site in Firefox. At this time, the site SSL certificate indicates secure status.

Thank you again for you interest and tips to resolve this issue.

No problems here with the certificate for this website and the report also looks good.

Try to rename the cert9.db file (cert9OLD.db) and remove the previously used cert8.db file in the Firefox profile folder with Firefox closed to remove intermediate certificates and exceptions that Firefox has cached.

If this has helped to solve the problem then you can remove the renamed cert9OLD.db file. Otherwise you can undo the rename and restore cert9.db.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).

I navigated to the Firefox profile file using the steps provided and changed the file to cert9OLD. I did not see the cert8 db file. I closed the folder, reopened Firefox and my website. It still shows as "not secure" on my PC. I then went back into the profile file. I saw two files: cert9OLD and cert9.

I'm probably missing something. Should I clear cache and see if that works?

Thank you.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

What do the security warning codes mean


Delete browsing, search and download history on Firefox {web link}

Remove a single website from your history {web link}

Open the History Manager <Control> (Mac=<Command>) <Shift> H. In the search bar, enter the name of the site. Right-click on one of the listings and select Forget About This Site. This should remove all information, including any site settings And Passwords.

Who is the issuer of the certificate ?

You can check details about the issuer of the certificate and the certificate chain.

Thank you all. I tried the "forget site" option. I continue to get the "not secure" description when I open the site in my Firefox.

By checking the SSL certificate using the suggested SSLLABS tool I can see that the certificate is working as it is supposed to. That was the reason for reaching out.

So I think the problem seems to be with my version of the Firefox browser. Therefore, because the issue is limited to my PC, I am at an end point and will not be pursing the matter further.

Start Firefox using Troubleshoot(Safe) Mode {web link}

A small dialog should appear. Click Start In Troubleshoot(Safe) Mode (not Refresh). Is the problem still there?

Do you get an error page with a possible 'Advanced' button that allows to inspect the certificate ?
