clear cache completely in Kubunu
After creating a new virtual website with a letsencrypt certificate there was an error. This error is fixed. The certificate is valid and checked. When I go to the website, I get no errors. But Firefox does not load the css-files from a subdirectory. I go to the source of the page, click on the css-file : nothing happens. I copy the link location and paste it in a new tab. I get the errors: "Warning: Potential Security Risk Ahead" "Error code: SSL_ERROR_BAD_CERT_DOMAIN" It seems, that Firefox remembers, that there was a problem. But this problem is solved. Accoring to ssllabs.com/ssltest/analyze.html the certificate is valid. Chrome thinks the certificate is valid. Firefox thinks the certificate is valid, but not for a css subdirectory.
I cleared the cache of firefox with 'privacy and security -> clear data'.
'Privacy and security -> clear history when firedox closes' is set with all settings enabled, including 'Offline website data'. After restarting Firefox the error is the same. Is this a bug or do I overlook something ?

Hello nula,
Follow the instructions and step :
1. Continue With an Insecure Connection
Some errors will allow you to accept the risk and continue. You can continue with the insecure connection at your own risk:
- Click on Advanced.
- Click on Accept the Risk and Continue.
Note: This trick will not work for the “SEC_ERROR_REVOKED_CERTIFICATE” and other sort of serious errors. If you don’t see this option, move on to the next solution.

3. Temporarily Disable Your Antivirus and Firewall
Some antivirus and firewall solutions are sensitive to SSL errors. To address this issue, all you need to do is turn off HTTPS scanning. All antiviruses have different SSL scanning under different names. Find the appropriate setting such as “HTTPS Scanning,” “Scan SSL”, “show safe result,” “Do not scan encrypted connections,” etc.,and disable it.
If you don’t see any such options, visit the manufacturer’s help section and try to find SSL- and HTTPS-related settings information there.

Thank you for your answers. Accepting the security risk worked. Most of the suggestions seem to be for windows, I work with kubuntu linux. In kubuntu 14 there were no problems. Last week I upgraded to kubuntu 20 with the latest version of Firefox. I am not very happy with the new version.
