How can I set Firefox 4 to warn me when it goes from a secure page to a non-secure page??? Easy in 3.xx.xx (Security->Security warnings), but how to do it in Ver 4?

In Firefox version 3.xx.xx I could set the browser to warn me when going into and out of a secure page by going to Tools->Options->Security->Warning Messages. In version 4, there is no "Warning messages" settings feature.

The only way I know to do this in Firefox 4 is to change hidden preferences.

  1. Type about:config into the location bar and press enter
  2. Accept the warning message that appears, you will be taken to a list of preferences
  3. In the filter box type security.warn this will show a few preferences, you can double-click on them to change their values, the settings are:
    1. security.warn_viewing_mixed -I'm about to view an encrypted page that contains some unencrypted information
    2. security.warn_submit_insecure - I submit information that's not encrypted
    3. security.warn_leaving_secure - I leave an encrypted page for one that isn't encrypted
    4. security.warn_entering_weak - I am about to view a page that uses low-grade encryption
    5. security.warn_entering_secure - I am about to view an encrypted page
