Features Tooltivity's expert score for the 'Features' aspect of each extension. | 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.
| 8.5 Ad blocking: The free version blocks annoying advertisements on websites. With the premium version, additional functions such as the blocking of cookie banners or pop-ups can also be activated. ![]() Privacy and Security: AdBlock blocks third-party trackers on every Website and protects your privacy. It also blocking malicious ads with malware, scams, and cryptocurrency miners. ![]() Sync & Backup: With the Premium version, whitelists and user-defined rules can be synchronized across Chrome profiles.

Performance Tooltivity's expert score for the 'Performance' aspect of each extension. | 9.5 In our test, we did not notice any delays or slowdowns due to the extension. Winner in this category | 8.0 The ad blocker extension generally works without slowing down the browser on most websites. However, recent changes at YouTube have meant that AdBlock has not yet managed to ban ads from YouTube again. |
Design Tooltivity's expert score for the 'Design' aspect of each extension. | 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. | 8.5 The user interface is clearly laid out. With the premium version, you can also use functions to make individual adjustments. You're in control of the look, feel, and font size of AdBlock with easy-to-use controls. There is also the Image Swap function, which will still block ads, but it will replace some ads with pretty pictures of cats, dogs, and nature. Winner in this category |
Value for Money Tooltivity's expert score for the 'Value for Money' aspect of each extension. | 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. Winner in this category | 7.5 The free version offers good value for money. Compared to other competitors, the premium functions may be somewhat more expensive. Some premium functions are offered free of charge by other providers. |
Ease of Use Tooltivity's expert score for the 'Ease of Use' aspect of each extension. | 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. ![]() Winner in this category | 7.8 Installation is done in one click. However, you are immediately redirected to a website that informs you that payment is required to use it. However, this is only a voluntary donation. ![]() |

Winner in this category | 9.0 Strong privacy protection through the premium feature malware blocking. The privacy policy is transparent without any indication of data being passed on. |
