Enabling cookies in Chrome is usually a one-minute task, but the right setting depends on what you actually want cookies to do. Cookies are the small records a site stores in your browser to remember you, and they fall into two broad categories. First-party cookies belong to the site you are visiting and keep you logged in, remember your cart, and save preferences. Third-party cookies belong to other domains and are the backbone of cross-site tracking and ad personalization. Chrome lets you control those two categories independently, which is the key to a fast, functional browser without handing your activity to every ad network.
What do cookies actually do, and why does Chrome let you control them?
A cookie is a small text file a website asks your browser to store. When you revisit the site, your browser sends the cookie back, and the server uses it to recognize you. Essential cookies handle authentication, session tokens, and load-balancing. Personalization cookies remember your language, region, and layout choices. The problematic category is tracking and advertising cookies, which are set by third-party domains embedded in the page and used to follow you across unrelated sites for ad targeting. Chrome exposes dedicated controls for each category so you can keep the convenience without the tracking.
How to enable all cookies on Chrome (Windows and Mac)
Open Chrome, click the three-dot icon in the top right, and select Settings. On the left menu choose Privacy and security, then click Third-party cookies. Select Allow all cookies. This turns on both first-party and third-party cookie storage. You can optionally tick Block third-party cookies in Incognito to keep private-window tracking limited while leaving normal browsing unrestricted.
This same screen also offers the standard Chrome cookie presets: Block all cookies, which breaks many sites; Block third-party cookies, the recommended middle ground; and Block third-party cookies in Incognito. For most users the third-party-blocking default is the best starting point, with exceptions added for the few sites that misbehave.
How to enable cookies on Chrome for Android
Open the Chrome app, tap the three-dot icon in the top right, then tap Settings. Scroll down and tap Site settings, then tap Cookies. Toggle Allow cookies on. To allow cookies for a single domain only, use the Add site exception field and enter the domain. This is the cleanest way to keep broad tracking blocked while fixing a site that insists on third-party cookies to log you in.
How to enable cookies on Chrome for iOS (iPhone and iPad)
Open Chrome, tap the three-dot icon in the bottom right, go to Settings > Privacy and security, then locate the Cookies option and make sure it is enabled. Chrome on iOS uses the same WebKit engine that Safari uses, so the toggles map closely to Apple’s privacy defaults. If a site still refuses to save cookies after you enable them, check Settings > Safari > Block All Cookies on the device level for overlap, then re-open Chrome.
How to allow cookies for specific sites only
If one site keeps logging you out while you want to keep third-party cookies blocked everywhere else, add a per-site exception. In Chrome for desktop, go to Settings > Privacy and security > Cookies and other site data, find the Sites that can always use cookies section, click Add, and enter the site URL. On Android the same option sits under Site settings > Cookies > Add site exception. This approach avoids opening the cookie floodgates globally just to fix one stubborn page.
Why this matters beyond staying logged in.
Cookies are the simplest implementation of a persistent identifier. A site you logged into weeks ago can still recognize you the moment you return, and a third-party tracker embedded across hundreds of unrelated sites can stitch together a profile of the pages you read, the products you view, and the searches you run. Letting all cookies through trades convenience for that profiling. The practical response is not to block every cookie, that quickly makes the web unusable, but to allow first-party storage by default and enforce a strict third-party boundary with targeted exceptions for the sites you trust.
Read the Manifest V3 overview to understand why network-level filtering matters for cookies and tracking, compare the best ad blockers, and check the transparency page for how a tracker-free setup changes the data your browser hands to third parties.
How ProBlocker addresses this
ProBlocker blocks the third-party tracking and ad scripts that rely on cross-site cookies without breaking the first-party cookies your favorite sites need to stay logged in. It is free, open source on GitHub, and collects no user data because all filtering runs locally. The extension is built native to Chrome’s Manifest V3 declarativeNetRequest API, so it continues to work in current Chrome builds. ProBlocker subscribes to EasyList, EasyPrivacy, and uBlock Origin filter lists updated daily, plus custom rules that counter YouTube ads, pop-ups, and malware domains, and it supports Chrome, Firefox, Edge, Brave, Opera, and Vivaldi. Install it from the Chrome Web Store or the download page.
How to manage and clear cookies after enabling them
Open Chrome > Settings > Privacy and security > Third-party cookies to adjust the policy at any time. To delete what is already stored, go to Privacy and security > Clear browsing data, check Cookies and other site data, choose a time range such as Last hour, Last 7 days, or All time, and click Clear data. If you want Chrome to clear cookies automatically when you close the browser, enable Clear cookies and site data when you close all windows on the same cookies page. For the most control, keep that auto-clear off and instead rely on per-site allow lists plus periodic manual clearing with the Custom range option.
