What are cookies?
Cookies are files created by websites you’ve visited that store browsing information, such as your site preferences or profile information. There are two types of cookies: First-party cookies are set by the site domain listed in the address bar. Third-party cookies come from other domain sources that have items such as ads or images embedded on the page.
You have complete control when it comes to cookie permission in Google Chrome. All cookies are allowed by default, but you can adjust this setting. If cookies have been set or blocked on the page that you’re viewing, an icon appears at the end of the address bar.
How to adjust cookie permission
- Click the spanner icon on the browser toolbar.
- Select Options (Preferences on Mac and Linux; Settings on a Chromebook).
- Click the Under the Bonnet tab.
- Click Content settings in the “Privacy” section.
- Click the Cookies tab in the Content Settings dialogue that appears:
Click All cookies and site data to open the Cookies and Other Data dialogue.
- To delete all cookies, click Remove all at the bottom of the dialogue.
- To delete a specific cookie, select the site that issued the cookie, then the cookie and click Remove.
Block cookies by default
Block all cookies
Select “Block sites from setting any data”. Keep in mind that selecting this setting will prevent most sites that require you to sign in from working. You’ll see blocked cookie image in the address bar whenever a cookie has been blocked.
Block only third-party cookies
Select the “Ignore exceptions and block third-party cookies from being set” checkbox. Even if you’ve added a site to the Exceptions list and have chosen to allow its cookies, the site’s third-party cookies won’t be accepted if this checkbox is selected.
Allow cookies by default
Make sure that “Allow local data to be set” is selected to allow both first-party and third-party cookies. If you only want to accept first-party cookies, select the “Block all third-party cookies without exception” checkbox.
Make exceptions for cookies from specific websites or domains
To control how cookies should be handled for a few specific sites or domains, click Manage exceptions. To add a rule in the Cookie and Site Data Exceptions dialogue that appears, follow these steps:
- Click the “Add a new exception pattern” field and enter the domain name for which you want to create an exception.
- To create exceptions for an entire domain, insert [*.] before the domain name (e.g. [*.]google.com).
- You can also specify an IP address, an IPv6 address or a non-http URL.
- You can use the menu to choose whether the site can set cookies. If you select Session only, its cookies are deleted every time you close your browser.
You may also edit or remove exceptions, using this dialogue.
