Looks nice but how can i open private tab via command line and navigate url ?

Questa recensione riguarda una versione precedente (0.1.3.1-signed) del componente aggiuntivo.

Since version 0.1.4 ( https://addons.mozilla.org/addon/private-tab/versions/0.1.4 ) can be used
firefox private:///#https://addons.mozilla.org/
(and all other URL-related command line things)
