+The favicon provider used for downloading icons if they are enabled in the user profile settings.
+The default provider is a Google service that automatically detects the correct favicon for a website, and provides icons in consistent image format (PNG) and in a consistent image size.
+
+This setting allows to configure a custom provider in form of a URL.
+When calling the provider with the URL of a website, it must return the image data for the favicon of that website.
+The configured favicon provider URL must contain a `{url}` placeholder that will be replaced with the URL of the website for which to download the favicon.
+See the default URL for an example.
