Avast Online Security and Firefox Private Window

Avast Free AntiVirus v11.2.2262
Firefox browser v46.0.1
When using a Firefox Private Window the Avast Online Security icon is not displayed so I do not know if it is active and I cannot see ratings or tracking block status etc.
I strongly suspect that it is not active when using a Private Mode Window since in a Google Search, the site safety icon is not displayed (Like it normally is for standard window mode)
Can anyone confirm if Online security is active when in Firefox Private Mode ? Or how to enable it ?

Note, on the Google Chrome browser, the Avast Extension can be enabled within incognito mode by ticking that option for the extension. This option to enable does not seem to be available in Firefox ?
