How to Disable the Insecure Login Warning in Firefox

Since it repeatedly annoys me to great effect, this is a reminder to myself as well as anyone looking to do the same. While locally developing web content, logging in to a CMS backend, you may have experienced this overlay:

This connection is not secure, Logins entered here could be compromised.

It won’t go away until clicked upon, which opens a website with further information. Useful for end users, frustrating for developers.

  1. Open about:config in Firefox.
  2. Search for key security.insecure_password.ui.enabled.
  3. Double-click the found entry and set to false.
