Security certificate errors in Zotero
Note: These instructions are only for use with security software that intercepts/scans HTTPS connections, a WebDAV server with a self-signed certificate, or an institutional network that monitors encrypted traffic using a custom root certificate authority (CA). You should never override certificate errors unless you understand the consequences. When in doubt please contact your network administrator or ISP.
Zotero does not currently provide a graphical way to whitelist self-signed certificates or custom root certificates, so you will need to copy files from a working Firefox installation:
- If you or your organization is using a custom certificate authority, which can be the case when using security software or connecting via a proxy server, you or your IT department will need to configure Firefox 52 ESR for the custom CA in a new Firefox profile and then copy the cert8.db, key3.db, and secmod.db files from the Firefox profile directory to the Zotero profile directory. (Later versions of Firefox will produce a cert9.db file that requires Zotero 5.0.78, which as of November 2019 is available in beta.)
