Security Sockets Layer version 3 (SSLv3), a type of technology that allows your browser to connect to a server, is no longer secure. This makes it easy for hackers to extract personal information during a connection. Firefox blocks SSLv3 to protect you from these attacks.
When you open a page that still supports SSLv3, you will see this error message: "Unable to connect securely". You can still access that website by telling Firefox to use a more secure certificate such as TLS. Here's how to configure Firefox so it will connect using TLS instead of SSLv3:
# Type ''about:config'' in your address bar and press {for win,linux}{key Enter}{/for}{for mac}{key return}{/for}.
# Find the appropriate preference by entering ''security.tls.version.min'' in the search field.
# Change the ''security.tls.version.min'' setting to '''1''', then click {button OK} to finish.
# Refresh the webpage to load it using the secure certificate.
