A favicon is an icon that is associated with a website and is displayed to the left of the website name in the browser tab. Favicons are also included in bookmark listings next to the website name.
Change your favicon image in Settings > Editor settings > Favicon.
Add a favicon to your website by uploading your favicon file or select it from your File Library and finish by clicking Save. Your favicon will be visible in the browser tab when your website has been published.
