You can now use the extension by clicking it and searching for the blog.
The domain name link opens the EBN page of the blog, and the icon logs you into the blog.
You can also visit the wp-admin page of the blog and click the button EBN Blog Login.
The browser extension uses EBN API to show and log into you into the blogs. Extensions do not have logs, do not save nor send blog or login lists. There is no data sent anywhere, it’s just local to your browser.
