Privacy & Security Preferences - SSL

This section describes how to use the SSL preferences panel. If you are not already viewing the panel, follow these steps:

  1. Open the &brandShortName; Edit menu and choose Preferences.
  2. Under the Privacy & Security category, click SSL. (If no subcategories are visible, double-click Privacy & Security to expand the list.)

SSL Protocol Versions

The Secure Sockets Layer (SSL) protocol defines rules governing mutual authentication between a web site and browser software and the encryption of information that flows between them. The Transport Layer Security (TLS) protocol is an IETF standard based on SSL. TLS 1.0 can be thought of as SSL 3.1.

You should normally leave all of the following checkboxes selected to ensure that both older and newer web servers can work with the browser:

Important note regarding TLS: Some servers that do not implement SSL correctly cannot negotiate the SSL handshake with client software (such as the browser) that supports TLS. Such servers are known as TLS intolerant.

When the Enable TLS 1.0 option in the SSL preferences panel is selected, the browser attempts to use the TLS protocol when making secure connections with a server. If that connection fails because the server is TLS intolerant, the browser will fall back to using SSL 3.0 (if enabled).

SSL Warnings

It's easy to tell when the web site you are viewing is using an encrypted connection. If the connection is encrypted, the lock icon in the lower-right corner of the browser window is locked. If the connection is not encrypted, the lock icon is unlocked.

If you want additional warnings, you can select one or more of the warning checkboxes in the SSL preferences panel. Some people find these warnings annoying.

To activate any of these warnings, select the corresponding checkbox:

For short definitions, click authentication, encryption, or certificate.
