This issue is affecting web sites to be opened in Firefox Browser (e.g. netPI's web GUI landing page) if self-signed certificates are used. It can be encountered when the certificate has been replaced multiple times by Firefox with new same certificates that all have identical Subject/Issuer information. This is the case if you restore your netPI to factory default and Firefox wants you to reaccept the untrusted certificate during the next browser session.
A way to correct this problem is to browse about:support in your Firefox address bar instead of an URL. Click then Open Folder under topic Profile Folder. Locate certx.db e.g. cert8.db in your file explorer and rename or delete it (e.g. “cert8.db.bak”). It may be necessary to have Firefox close to access the file.
Start your Firefox and visit netPI's landing page again and the problem is gone.
