Turn your browser into some kind of a web-api for tabs, bookmarks and history. The mozeidon add-on listens to various commands (e.g 'get-tabs') sent by the mozeidon native-app, and sends back various json responses (e.g current tabs) to the mozeidon native-app. Please read about and install the native-app available here : https://github.com/egovelox/mozeidon-native-app/ At last, you'll be able to use the Mozeidon CLI to get your tabs, bookmarks, history, etc : https://github.com/egovelox/mozeidon Available commands the mozeidon add-on listens to :

"close-tabs" : the mozeidon add-on will close one or more tabs.
"get-bookmarks" : the mozeidon add-on will respond bookmarks in json.
"get-history-items" : the mozeidon add-on will respond history in json.
"get-recently-closed-tabs" : the mozeidon add-on will respond recently-closed tabs in json.
"get-tabs" : the mozeidon add-on will respond currently-opened tabs in json.
"new-tab" : the mozeidon add-on will open a new tab.
"switch-tab" : the mozeidon add-on will switch to a specific tab.

These available commands (and their arguments) are sent by the mozeidon CLI through the mozeidon native-app to the mozeidon add-on.
