The Impact of Chrome Manifest V3 on Ad Blockers and User Experience

1. Introduction

The internet has become an indispensable element in our daily lives today. However, at the same time, various unnecessary ads that hinder the web surfing experience are increasing. Many users install ad blockers to maintain a comfortable internet environment.
Ad blockers provide a more focused web environment by automatically detecting and filtering unnecessary content. They also contribute to reducing unnecessary data usage and improving page loading speeds.
The Chrome browser is currently one of the most popular web browsers in the world, with a market share of over 60%. This is thanks to its attractive user interface and diverse extensions. Among these, the ad-blocking feature has become an essential tool for many users.
However, recently, with Google introducing a new policy called "Manifest V3" to Chrome, this situation might change significantly. In this article, we will explore the concept of Manifest V3 and its potential impact on popular ad blocking programs like uBlock Origin.

2. What is Manifest V3?

Manifest Version 3 (Manifest V3) is a new web extension API developed by Google. It was introduced to enhance the security and efficiency of the browser. Many of the features supported by the previous Manifest V2 are expected to be changed or restricted, which is anticipated to have a direct impact on many extension programs.
Manifest V3 particularly focuses on enhancing security-related technologies. For example, by eliminating risk factors such as the execution of remote code and arbitrary strings, it aims to reduce attempts at malware and hacking. It is also designed to use resources more efficiently, so performance improvements are expected.
Through these changes, Google aims to build a safer and more reliable online environment. However, since these changes require significant alterations in how conventional extension programs operate, concerns are rising among some users. Especially if popular ad blocking tools like uBlock Origin cease to function, many users might feel inconvenienced.

3. uBlock Origin and Its Impact

uBlock Origin is a powerful ad blocker provided for free and in open-source form. Currently, this tool has over 34 million users and is widely known, not only on Chrome but also on many other browsers. Its main functions include removing banner and video ads as well as blocking scripts and trackers, making it highly effective. Users can choose or customize filter lists to suit their needs, allowing for a personalized internet experience.
However, with Google's announcement of the plan to apply Manifest V3, the uBlock Origin development team has expressed serious concerns. Raymond Hill, the founder of uBlock Origin, stated that "the introduction of Manifest V3 will render existing functions powerless and, in the worst-case scenario, strip users of their content control rights." As a result, the Chrome Web Store now displays a warning message stating, "This extension may soon be unsupported because it does not comply with Chrome extension recommendations," and even recommends alternative apps, increasing the seriousness of the matter.

4. Issues Due to Chrome Extension Policy Updates

One of the biggest issues with the transition from Google's Manifest V2 to Manifest V3 is the potential end of support for existing extensions. Various extensions that many people relied on may no longer be usable in the future. Particularly, major applications for security, such as ad blockers and antivirus software, will be significantly affected.
Negative impacts on user experience are also expected. If pop-ups and banner ads randomly appear while browsing again, the comfort and convenience many people felt will be lost. This will negatively affect the overall internet experience. Additionally, alternative solutions like "uBlock Origin Lite" and other substitutes provide more limited functionality than existing products, making it likely they will not meet user expectations. Therefore, it is questionable how many users will be satisfied and continue to use these platforms amidst such policy changes.

5. Alternatives and Use Cases

So, how should we cope under Google's new policy? The first option to consider is "uBlock Origin Lite." Even with somewhat limited functionality, it provides basic ad-blocking services. However, its performance is lower than the existing uBlock Origin and may cause disappointment.
Another alternative is privacy-focused browsers like Brave or Firefox. However, the benefits obtained through these are also somewhat limited. In fact, whichever option is chosen, there is a high possibility of remaining shortcomings and dissatisfaction. Ultimately, many users may find it difficult to find a clear solution other than sharing alternatives with each other and optimizing according to their needs. There will be more exchanges of information through various forums and community sites to find ways to maximize performance and recommended solutions. Therefore, we need to continue exchanging opinions and exploring how to utilize them appropriately.

6. Comparison of KakaoTalk Updates and Related Technology Changes

Recently, KakaoTalk also underwent a major update (v11.0), particularly considering user convenience. One of the updates, the addition of the "Fake Signal" menu to alert about fraud/impersonation profiles, is noteworthy for its attempt to strengthen specific personal information protection measures.
Comparing and analyzing the two technologies, it can be confirmed that both aim to enhance security and emphasize user protection. However, the themes each system is trying to address are also contrasting. In the case of Chrome, it is attempting to remove certain types of add-ons, whereas within the KakaoTalk system, proactive defensive measures are being implemented. Therefore, the operational methods and awareness of purposes set by each platform are also considered an interesting subject of discussion. It is crucial to understand how both systems will evolve in the future and the points of conflict that will arise in the process.

7. Conclusion: Future Prospects and Questions for Readers

As we face the current changes, we need to think about what kind of future is unfolding. Changes in ad-blocking technology and browser policies will require us to readjust our lifestyle patterns. Therefore, I believe we need to find appropriate coping methods tailored to each necessary condition.
"What are your perceptions of this policy change by Google? And do you see it as an opportunity to switch to other browsers?"
We look forward to your feedback!
