Compare Decentraleyes, AdGuard AdBlocker, AdBlocker Ultimate, and AdBlock Max: Which Extension is the Best?

AdBlock Max offers comprehensive functions for blocking advertising, including pop-ups, banners, and video ads.

Ad blocker
A slider can be used to set how thoroughly websites should be searched for advertisements, etc., to block them. Depending on the filter method, the extension must be granted more permissions.

In addition to these basic functions, there are other functions such as blocking cookie notifications or increasing Internet security through tracking protection.

These additional functions are hidden at the bottom of the settings and can be activated. There is also a website whitelist on which no advertising should be blocked.

Privacy Security
Privacy protection functions automatically prevent tracking and protect user data.

A recent user complained in a review that it had YouTube problems that affected the performance and speed of the website. In our test, we did not notice any performance problems.

The design is very clear and well-organized. The display of the settings is significant for adblockers. Here, great importance has been attached to user-friendliness and highlighting the customizable settings.

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.

The user interface is clear and intuitive. In particular, the filter customization options are very clearly displayed in the extension pop-up.

The free browser extension offers numerous functions that worked perfectly in the test. Compared to competitors, you get many functions here that others offer for a fee.
If further functions are required that can also be used outside the web browser, AdGuard Adblocker also offers an app that is subject to a charge. We consider the current lifetime prices to be fair for the services offered.

If you take a closer look at the extension in addition to the basic functions, you will see how many additional functions are available. As a free web extension, the price/performance ratio is very good.

What impressed us in comparison to other competitors was that AdGuard Adblocker clearly shows which functions it offers and explains them in the introduction, and you can activate them directly if you wish. The extension therefore attaches great importance to ensuring that every user recognizes and uses the options. With competitors, some functions were somewhat hidden in the settings.

The tool is uncomplicated and easy to install. Due to the well-designed method of a slider for the strength of the filter mode, preferences are easy to configure for everyone.
The other functions are easy to activate, but some users may find it difficult to understand which function does what. For each function, there is a description with the corresponding filter code on GitHub.

Overall, AdGuard provides transparency in its privacy policy and limits data collection. Some practices, such as filing public complaints and reviewing website visits, should be critically questioned.

However, it is not entirely transparent in the policies whether the data collected by the extension is passed on to third parties.
