A Quick Look at the Fate of Third-Party Cookies: Why Are They No Longer Relevant?

Third-party cookies remained an integral part of many websites by supporting their functionality. Today, the situation is slightly different. Due to rising security and privacy concerns, web standards bodies are emphasizing the need to remove them from websites. Safari, Edge, Chrome, and Firefox have already started taking steps in this direction to protect user privacy. However, this is not a straightforward process. Many necessary functionalities depend on third-party cookies, including embedded services and single sign-on. They also help minimize fraud. While third-party cookies have not yet been completely removed, developers need to remain vigilant about their status. With proper awareness, they can ensure that their sites’ functionality is not disrupted.

What should you do? If you don’t have an in-house expert team, you should look for a local web design firm and partner with it. They can be helpful in this area for several reasons.

What’s happening with cookies?

Experienced developers can responsibly handle the phaseout stages of third-party cookies and redesign integrations with privacy at the core. They also know that this will not be a sudden or dramatic change. Instead, removing cookies will be time-consuming. A few sites may have stopped using third-party cookies. Users may not realize this, but they may likely face problems with specific website features.

For a better understanding, let’s analyze a travel site. These sites usually rely on third-party iframes for live flight and train tracking. Cookies help them with authentication and content personalization. If a browser bans third-party cookies, the iframe will not be able to access any data. As a result, login issues or other errors may become prevalent. That’s why it’s essential to stay alert and take timely action.

Extensive knowledge of different browser behaviors

The success of any detection method depends on how each browser handles third-party cookies. Since the release of version 13.1, Safari has blocked third-party cookies entirely, regardless of whether a user has previously engaged with the embedded domain. As far as Firefox goes, it handles cookies based on the specific site. As a result, you can see that third-party cookies are still used, but they cannot be shared across sites.

Chrome still allows third-party cookies, but the rules have changed slightly. With Chrome 80, it became necessary to mark third-party cookies as secure. Google had initially announced that it would remove third-party cookies by 2022, but nothing happened until 2024. Google clarified that it would not eliminate third-party cookies or force users to adopt a new model without their consent. To align with this approach, Chrome is moving toward a user-focused interface. As a result, individuals will have more control over how third-party cookies are applied.

Without this understanding, managing the evolving challenges of third-party cookies can be difficult. That is why partnering one should partner with experienced site design and development professionals. If you need help with your website, consider visiting BigDropInc.com.
