-### HTTPS-Only Mode
-Betterfox already [blocks](https://github.com/yokoffing/Betterfox/blob/df5fc26a1bdccd30e01f3c1dfe69a09a2c050410/Securefox.js#L810-L827) HTTP subresources from loading on HTTPS pages. We also [attempt to upgrade](https://github.com/yokoffing/Betterfox/blob/df5fc26a1bdccd30e01f3c1dfe69a09a2c050410/Securefox.js#L545-L550) all site navigation, only falling back to insecure connections when a website does not support it.

-> [!WARNING]
-> HTTPS-Only Mode sometimes causes annoying navigational errors when using DoH. <br>
-
-> [!NOTE]
-> HTTPS doesn't mean "trust this." It means "this is private." <br>
-> You may be having a private conversation with Satan. <br>

-// PREF: enable HTTPS-Only Mode
-// Warn me before loading sites that don't support HTTPS
-// when using Private Browsing windows.
-user_pref("dom.security.https_only_mode_pbm", true);
-user_pref("dom.security.https_only_mode_error_page_user_suggestions", true);
-```
-
-#### Option 2: All windows

-// in both Normal and Private Browsing windows.
-user_pref("dom.security.https_only_mode", true);

 ### Captive portal detection
 Captive portals allow you to connect to public Wi-Fi by redirecting to login pages (think hotels, airports, etc.). You can safely disable Mozilla's [captive portal detection](https://support.mozilla.org/en-US/kb/captive-portal) on most **desktop** computers.
