The browsingData.RemovalOptions type contains options to control certain aspects of browsing data removal.


Values of this type are objects. They contain the following properties:

hostnames Optional

Array of string. This property only applies to cookies and local storage items. Only remove cookies and local storage items which are associated with these hostnames.

You must pass in just a hostname here, without protocol (for example: "google.com" not https://google.com"). You can use the URL interface to parse a raw URL and retrieve just the hostname. Items associated with subdomains of a given hostname will not be removed: you must explicitly list subdomains.

originTypes Optional

object. Used to control whether to remove data only from normal web pages, or also from hosted web apps and extensions. If this option is omitted, only data from normal web pages ("unprotectedWeb") is removed. Before removing data from web apps or extensions, be very careful to ensure that this is really what the user wants.

This object may contain any of the following properties:

unprotectedWeb Optional
boolean. If present and true, remove data from normal web pages.
protectedWeb Optional
boolean. If present and true, remove data from websites that have been installed as hosted apps.
extension Optional
boolean. If present and true, remove data from extensions.
since Optional
number. How far back in time to remove data, given in milliseconds since the UNIX epoch. Note that when removing the browser cache, the entire cache is always removed and this option is ignored. If the since property is omitted, it defaults to 0, which means "forever".
