While they remember your login details, they can also track your browsing history, display targeted ads, or even hijack your active browser session. To strike a balance between usability and security, you need to understand and manage your browser cookies effectively.

Device Bound Session Credentials: A Game-Changer in Chrome
Chrome’s Device Bound Session Credentials (DBSC) feature restricts session cookies to your current physical device only. This hardware-bound restriction prevents hackers from replaying your session cookies from a different device. DBSC is turned on by default in Chrome version 146 and above, but you need to enable TPM on Windows for it to work.

Managing Cookies in Firefox: The Multi-Account Containers Extension
Firefox’s Total Cookie Protection feature creates a separate cookie jar for each domain, preventing third-party cookies from tracking you. However, this feature has limitations when dealing with multiple accounts on the same domain.

- Search for the ‘Multi-Account Containers’ extension in the Firefox Add-ons store.
- Click the ‘Add to Firefox’ button to install the extension.
Safari’s Cookie Management: Intelligent Tracking Prevention (ITP) and Beyond
Safari’s ITP feature has been protecting users from tracking and cookies since 2017. However, there are additional features to explore, including Advanced Tracking and Fingerprinting Protection (ATFP) and Advanced Fingerprinting Protection (AFP). These features work together to provide an extra layer of security for your browsing activity.
How to Adjust Your Privacy Settings on Safari

Temporary Cookie Permissions: A Middle Ground for Enhanced Security
Instead of blocking third-party cookies outright, you can create temporary exceptions on a per-site basis for websites that need cookies enabled. This feature is particularly useful for websites that require cookies for complete functionality.
How to Create Temporary Cookie Permissions in Chrome
To create temporary cookie permissions in Chrome, follow these steps:
- Click on the eye-shaped icon next to the address bar.

Revoking Active Sessions: A Crucial Security Measure
Passkeys protect your login credentials, but not the logged-in accounts on your web browser. If an attacker gains access to your session cookies through malware or phishing, they can freely access your accounts as long as your current browser session remains active. To mitigate this risk, revoke your active sessions once you’re done with an app or website.
How to Revoke Active Sessions on Your Device
To revoke active sessions on your device, follow these steps:
- Log out of the account from the device.
- Revoke active sessions tied to your account either per device or all at once.
Implementing Network-Level Blocking with DNS Filters
Not all browsers support cookie management extensions on every device. In such cases, implementing network-level blocking with DNS filters can provide an additional layer of security. This feature is particularly useful for users who need to block specific websites or IP addresses.
How to Implement DNS Filtering on Your Device
To implement DNS filtering on your device, follow these steps:
- Enable DNS filtering on your router or device.
- Configure the DNS filter to block specific websites or IP addresses.
