Hi,

When I tried to clear the storage.local, there is a problem.

1. I open a popup and I tried to clear.  
With this code : **browser.storage.local.clear();**  

2. It’s clear yeah ! But when I refresh the storage.local it’s back …  

Available here : [https://addons.mozilla.org/en-US/firefox/addon/navigation-stats-plus/](https://addons.mozilla.org/en-US/firefox/addon/navigation-stats-plus/)

So I really don’t know what happen. If anyone know it and can help me, thanks.

`browser.storage.local` is **not** `localStorage`!

> **[storage.local](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/storage/local)**
>
> Represents the local storage area. Items in local storage are local to the machine the extension was installed on.

> **[Window.localStorage](https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage)**
>
> The read-only localStorage property allows you to access a Storage object for the Document's origin; the stored data is saved across browser sessions.

Your hostNavigationStats has not been cleared, and it also reside in the background as global object.
