How to:
1. On the "preference" of this addon, enter your site url that hosts leaf (i.e. `https://example.com`). You should exclude the trailing slash.
Also, enter WEB_API_TOKEN you set in `.env.production`.
2. Then click the icon on the toolbar to add the page you read now to leaf. Also you can add the link or page itself from the context menu (from v0.2.0).
