Not great! Instead of using an icon on the toolbar and having a settings menu that contains all the settings --- like normal extensions for Firefox for the past decade or so ---this app takes over your New Browser Tab -- which is where you actually control the rest of the settings.
I'm not comfortable having an extension that: - Needs to have it's own tab to work. - Takes over my new tab, where I keep important bookmarks. - Does not have a toolbar icon. This seems suspect to me, why would you want me to forget that this extension is on my machine? - Splits settings into two wildly different interfaces.
