Features	9.3 AdBlocker Ultimate offers a wide range of features that effectively block ads on websites, YouTube and social media platforms. Ad Blocking: Ads are prevented on various platforms, both on the website and as pop-ups. There are other additional functions here, such as blocking all irritating in-page popups, cookie notices and third-party widgets, which substantially decrease page loading times. The settings can also be used to remove only country-specific advertising and a whitelist can be added. Privacy Filter Blocks an extensive list of various online trackers, counters and web analytics tools. Based on the EasyList Privacy list and upgraded by our team. Additionally you can use the Fanboy's Social Blocking List which Removes social media integration. Security: The Security Filter automatically blocks all malicious domains. The listed filters can all be switched on and off separately and individually.	8.5 Nowadays, websites request data through third parties. The local CDN emulation offered by Decentraleyes is a unique and effective feature that blocker competitors currently lack. This means that the same locally stored data is always sent directly to the websites before they can even request relevant private data. The extension is aware that this function is only an additional function and advertises it as being used in addition to regular ad blockers. The extension could be expanded here and offer these additional functions directly so that you have them all in one extension. Another advantage of the extension is that the code is completely open source and can be found on GitLab. This ensures transparency and trust.	7.5 The core function that One Sec uses to make users more productive is a pause before opening the website. When I open websites I have defined, such as Twitter, a gray page with a countdown appears. During this period, I was reminded that I didn't want to spend so much time on Twitter and asked myself whether this was intentional or just a reflex out of boredom. This worked very well for us in the test and there were no problems. It is also possible to adjust the delay individually. If you only need the reminder but don't want to be disturbed too much, you can set the timer to just one second, or several seconds if you prefer. Finally, a useful function is the analysis dashboard. This provides analyses of your surfing behavior, showing you at a glance how often you try to open these websites during the day. However, we would like to see more analysis options here. All in all, the functions are kept very simple; further options for time tracking would be an advantage here so that you don't need additional extensions. These functions are already available in the mobile app. One Sec is a good addition to existing time management extensions.
Performance	9.0 During our test, AdBlocker Ultimate did not experience any performance issues. Ad blocking worked flawlessly on all platforms tested, so there were no disruptions to websites caused by advertising.	9.3 The extension offers a noticeable improvement in page load times. We did not find any problems in our tests, but according to user reviews, there are occasional compatibility problems with certain websites. However, according to Decentraleyes, these are constantly being fixed by updates.	9.5 In our test, we did not notice any delays or slowdowns due to the extension. Regular updates are also released to improve performance and fix bugs.
Design	8.5 The user interface is clearly laid out and should be easy to use for every user. The settings page is also very clearly laid out. Only the constant reference in the extension pop-up to the paid Windows desktop version detracts somewhat from the design.	9.5 The design is intuitive and simple. This also includes the settings menu.	8.0 The user interface is clean and minimalist, and this also applies to the setup and settings. The extension offers an effective use of visual elements for taking a break by displaying a preset screen with a countdown. There would be potential for improvement here if the screen could be customized.
Value for Money	9.5 The Web Extension is free of charge. Compared to other free providers, it offers a very high number of functions and options for customizable functions. We would therefore rate the price-performance ratio as very good.	9.5 The extension is completely free to use with optional donations. The price-performance ratio is therefore perfect, as functions that are not offered by other providers are made available here free of charge. Only the lack of further functions in the area of ad blocking results in deductions.	9.2 The browser extension is completely free of charge. However, you only get a small number of functions. For anyone who only needs the basic function, this is unbeatable value for money. OneSec also offers an app with additional functions. At $4.99/month or $49.99/year, it also has a good price-performance ratio.
Ease of Use	9.0 AdBlocker Ultimate is easy to install and can be used immediately afterwards. Even beginners should find the extra functions easy to use, as they are described in detail. Great importance has been attached to the individual settings for each user.	9.9 The extension is characterized by its user-friendliness. Installation is very simple and you have the option of testing the function immediately on the website. When you open the website https://decentraleyes.org/test/, you are shown whether the function works and an example of what it looks like in the icon when data is blocked. The settings are also very well described so that even beginners should have no problems here. Advanced users can also read the complete documentation or the code on GitLab.	9.5 The installation process was quick and straightforward. This also includes the setup, which is very intuitive with clear step-by-step instructions. Everything is also well explained in the settings menu afterward, so everyone should be able to find their way around.
Security & Privacy	8.2 The tool offers the function of extra privacy protection by preventing tracking and thus increasing online security. However, it is not entirely transparent in the policies whether the data collected by the extension is passed on to third parties.	9.2 The extension offers strong features in the area of data protection, so it goes without saying that it scores well in this area. The open-source code allows anyone to review the extension in detail. Only the lack of a proper privacy policy detracts from this for beginners, who can do little with the code. There is a privacy policy that states in one sentence that no data is collected. However, this should be a little more detailed.	9.5 Data usage is described transparently in the privacy policy, which places great value on user privacy. This is also reflected in the fact that the features already work with minimal authorizations so that not much private data needs to be tracked.
Conclusion	AdBlocker Ultimate is a great extension for blocking ads. Ads on various platforms are removed without the user noticing. Particularly noteworthy are the various options for customizing the settings. The user can control whether the extensions should only be responsible for blocking ads or whether they should also offer support in the areas of data protection and security. Compared to other ad blockers, the additional function of blocking cookie banners stood out, which we no longer want to do without. Overall, we consider AdBlocker Ultimate with its wide range of additional functions to be a reliable option for anyone who wants to remove advertising from their online experience.	Decentraleyes is a valuable tool for anyone who wants more privacy and faster browsing. With local CDN emulation, Decentraleyes has features that bring both security and performance benefits. While it currently excels in this one area, you need to be aware that websites also make adjustments and it won't always work 100% of the time, especially without further updates. Overall, Decentraleyes is a recommended choice for privacy-conscious users as an addition to the usual ad blockers.	One Sec is a tool that encourages mindful browsing by introducing a pause every time you want to access a distracting website. Although it stands out for its simplicity and effectiveness, its limited functionality means that it should only be seen as a supplement in the area of time management. Overall, however, it is a valuable tool for anyone looking to improve their online productivity.
