Here, you can activate language-specific filters, which automatically apply after detecting page language, and enable Anti-Circumvention to counteract websites that attempt to block ad blockers.
/images/2024/10/30/adblocker_ultimate_review_1024_refresh_18.png)
Overall, our experience was very positive, highlighting the ad blocker's ease of use and effectiveness in creating a cleaner browsing environment.
While AdBlocker Ultimate offers a free version, it also has paid plans that range from $1.25/mo (billed annually) and $2.49/mo (billed annually).

AdBlocker Ultimate allows you to decide exactly what you want to block or allow, from whitelisting your preferred sites to customizing blocking preferences through Custom Rules (advanced blacklisting). Additional capabilities include blocking ads and trackers in web browsers and Windows applications. It also safeguards against malicious domains.
AdBlocker Ultimate excels in removing disruptive elements like banners, video ads, and pop-ups while ensuring your browsing remains private by blocking online trackers. This dual functionality enhances both the usability and security of your web browsing experience across various web browsers.
AdBlocker Ultimate is not limited to web browsers. It extends its protective capabilities to Windows applications too. It blocks display ads, video ads, pop-ups, and trackers in many Windows-based applications, providing a comprehensive ad-blocking experience that transcends the web browser.

/images/2024/10/30/adblocker_ultimate_review_1024_refresh_16.png)
The Custom Rules feature acts as an advanced form of blacklisting, providing granular control over blocking decisions. This tool allows you to specify detailed conditions under which ads, trackers, and other elements are blocked or allowed, offering a powerful customization tool for tech-savvy users.
/images/2024/10/30/adblocker_ultimate_review_1024_refresh_17.png)
However, while powerful, it may present a learning curve for those unfamiliar with ad-blocking specifics.
One of AdBlocker Ultimate's standout features is its ability to block access from malicious domains known for distributing malware, phishing, and scam content. This proactive security measure helps protect you from potential threats before they can cause harm, significantly enhancing online safety.
AdBlocker Ultimate offers robust customization options through its ability to enable or disable ad filters and create personal rules. This feature allows you to tailor ad-blocking preferences to your specific needs, making it a versatile tool for personalizing web and app interactions.
To evaluate AdBlocker Ultimate, we used key testing tools to ensure its effectiveness. AdBlock Tester checks its ability to block various ad types, EFF’s Cover Your Tracks assesses privacy protection against tracking, and Can You Block It tests resistance to intrusive ads and anti-adblock defenses.
Our results show AdBlocker Ultimate scored 91/100 on AdBlock Tester, 2/3 on Cover Your Tracks, and 2/3 on Can You Block It, highlighting its reliable performance in ad blocking and privacy.
In AdBlock Tester, AdBlocker Ultimate was unable to block error monitoring (a type of analytics tool). Blocking these sentry scripts can help speed up your page load time, so not passing this component isn’t a dealbreaker.
/images/2024/10/30/adblocker_ultimate_review_1024_refresh_05.png)
Similarly, AdBlocker Ultimate was unable to obscure our digital fingerprint in the Cover Your Tracks testing, meaning that we could still be tracked online. However, most premium ad blockers (and even anti-tracker privacy tools) don’t pass this component. It still provides strong protection against online tracking.
/images/2024/10/30/adblocker_ultimate_review_1024_refresh_06.png)
For Can You Block It, AdBlocker Ultimate still let an interstial ad slip, but it blocked the banner ad and disable ad blocker warning. This is more annoying than concerning.

It's annoying to encounter paywalls while trying to access high-quality journalism and content. To assess AdBlocker Ultimate's ability to circumvent these paywalls, we tested it on several prominent news sites, including The Wall Street Journal, Bloomberg, and The Atlantic.
AdBlocker Ultimate was unable to bypass the robust paywalls set by these major publications, but this is common for most ad blockers. While it effectively blocked ads on these sites, users looking to access paywalled content without a subscription will find that this ad blocker doesn’t offer a solution for such restrictions.
AdBlocker Ultimate is compatible with a broad range of browsers, ensuring that users can enjoy uninterrupted, ad-free browsing regardless of their preferred platform.
While AdBlocker Ultimate covers most major browsers, it may not support less common or outdated browsers. On mobile devices, the ad blocker performs exceptionally well with a dedicated version for Android and a tailored extension for Safari on iOS, ensuring mobile users can also benefit from its features.
AdBlocker Ultimate also offers a download specifically compatible with PC and Windows OS.
We installed AdBlocker Ultimate as a Chrome browser extension on a macOS device. Following the installation, we opened Chrome and clicked the puzzle icon in the toolbar to access the Extensions menu.
We then pinned AdBlocker Ultimate to the top of the browser for easy access. Upon visiting websites, such as HuffPost, the extension was automatically enabled and operational in real time.
/images/2024/05/20/adblocker_chromeextension.png)
The AdBlocker Ultimate icon turned red, indicating it was active, and it immediately blocked dozens of ads. We could easily interact with the extension by clicking on the icon to adjust settings, toggle filters, and configure our custom filtering preferences, including advanced blacklisting and whitelisting rules.
