// TODO : Get the toolbar icons from Firefox's build (Nikki needs to give us a red saved icon)
// TODO : [needs clarificaiton from Fx] Firefox's plan was to hide Pocket from context menus until the user logs in. Now that it's an extension I'm wondering if we still need to do this.
// TODO : [needs clarificaiton from Fx] Reader mode (might be a something they need to do since it's in html, need to investigate their code)
// TODO : [needs clarificaiton from Fx] Move prefs within pktApi.s to sqlite or a local file so it's not editable (and is safer)
// TODO : [nice to have] - Immediately save, buffer the actions in a local queue and send (so it works offline, works like our native extensions)
