### Extensions
Control the installation, uninstallation and locking of extensions.
-While this policy is not technically deprecated, it is recommended that you use the **[`ExtensionSettings`](#extensionsettings)** policy. It has the same functionality and adds more. It does not support native paths, though, so you'll have to use file:/// URLs.

+| security.disable_button.openCertManager | string | N/A
+| If set to true and locked, the View Certificates button in preferences is disabled (Firefox 121, Firefox ESR 115.6)

| If set to true, adds the words "Not Secure" for insecure sites.

`"user"` preferences persist even if the policy is removed, so if you need to remove them, you should use the clear policy.
+You can also set the `Type` starting in Firefox 123 and Firefox ESR 115.8. It can be `number`, `boolean` or `string`. This is especially useful if you are seeing 0 or 1 values being converted to booleans when set as user preferences.
