+A new variable which has the `boolean` type
+===============================================
+
+.. objectives:: Objectives
+
+   In this section we will learn:
+   
+   - how to make a boolean type variable
+
+.. prerequisites:: Reminders
+
+   Let's summarize the configuration up to here
+
+Whe have the `proxy_mode` configuration here: 
+
+.. extinclude:: https://forge.cloud.silique.fr/stove/rougail-tutorials/raw/tag/v1.1_030/firefox/00-proxy.yml
+   :language: yaml
+   :caption: firefox/00-proxy.yml
+
+..

+    proxy_mode:
+      description: Configure Proxy Access to the Internet
+      choices:
+        - No proxy
+        - Auto-detect proxy settings for this network
+        - Use system proxy settings
+        - Manual proxy configuration
+        - Automatic proxy configuration URL
+      default: No proxy
+
+With the manual subfamily in case of the "Manual proxy configuration" configuration option has been chosen:
+
+.. extinclude:: https://forge.cloud.silique.fr/stove/rougail-tutorials/raw/tag/v1.1_030/firefox/10-manual.yml
+   :language: yaml
+   :caption: firefox/10-manual.yml
+
+..

+    manual:
+      description: Manual proxy configuration
+      disabled:
+        variable: proxy_mode
+        when_not: 'Manual proxy configuration'
+
+      http_proxy:
+        description: HTTP Proxy
+
+        address:
+          description: HTTP address
+          type: domainname
+          params:
+            allow_ip: true
+
+        port:
+          description: HTTP Port
+          type: port
+          default: 8080
+
+.. type-along:: The HTTPS mode 
+
+Now we will focus on configuring the HTTPS mode in case of "Manual proxy configuration".
+
+.. image:: images/firefox_manual_https.png
+
+Do we want to reuse, for the HTTPS mode, the same configuration as for the HTTP mode?
+
+A new `boolean` type variable
+-------------------------------
+
+We have a new variable, named `use_for_https` here:
+
+.. confval:: use_for_https
+   :type: `boolean`
+   :default: `true`
+
+   This is a setting that enables to reuse the HTTP proxy configuration for HTTPS
+
+Its description in the structure file gives us this:
+
+.. extinclude:: https://forge.cloud.silique.fr/stove/rougail-tutorials/raw/tag/v1.1_030/firefox/20-manual.yml
+   :language: yaml
+   :caption: firefox/20-manual.yml
+
+.. 
+    ---
+    manual:
+
+      use_for_https:
+        description: Also use this proxy for HTTPS
+        type: boolean
+        default: true
+
