What does “Your connection is not secure” mean?
Waterfox shows a warning when a site’s secure connection cannot be verified. This helps protect you from attackers and misconfigured sites.
Common causes:
- The site’s certificate is expired, invalid, or not issued by a trusted authority.
- A proxy, antivirus, or network is intercepting connections (MitM).
- Your system clock is incorrect.
