Total Adblock: Best for blocking mobile ads

Best Basic Adblocker — Including YouTube Video Ads

Ad Blocker
Total Adblock
Special deal: Save 75% off
  • Instantly blocks distracting ads on millions of websites, including YouTube video ads
  • Blocks third-party trackers to protect your privacy and information
  • Improves page load times and enables faster browsing
  • Free version excludes top 15,000 websites

Total Adblock is made by the same company that makes TotalAV antivirus, so you can be sure this ad blocker has cybersecurity chops. While testing it, we found it extremely easy to set up and really enjoyed the fact that we didn't have to manage any settings to block ads.

What we liked

Total Adblock received a perfect AdBlock Tester score and passed 2/3 Cover Your Tracks tests. AdBlock Tester tests the effectiveness of your ad blocker, factoring in contextual advertising, analytics tools, banner ads, and error monitoring. Cover Your Tracks tests your browser to see how well you're protected from tracking and fingerprinting. These high test scores are important, especially if you choose to pay for an ad blocker — no one wants to pay for something that doesn't work.

Needless to say, Total Adblock cleared out those annoying ads. The paid version blocks unlimited ads, disables browser notifications, and comes with antivirus protection, three bonuses that help keep your online adventures secure and annoyance-free.

Total Adblock's browser extension makes it easy to see how many ads it's blocked as well as toggle it on and off.

We also like that Total Adblock has iOS and Android apps for mobile devices, which can help protect your smartphone even more than a browser extension.

What we didn’t like

We wish Total Adblock's paid plan wasn't so expensive. The starting price is Free, but after that, you can expect to pay over $100 each year.

Keep in mind this high price might be worth it if you don't already have antivirus protection installed. Antivirus software is necessary for all devices, and you'll get access to the TotalAV security suite features if you pay for Total Adblock.

Total Adblock pros and cons

Pros
  • User-friendly setup and design
  • Hands-off ad blocking works in the background
Cons
  • Paid plan shoots up in price after first year

NordVPN Threat Protection: Best for blocking malicious ads

Enjoy Privacy and Security Even When Not Connected to a VPN

Ad Blocker
NordVPN Threat Protection
Save up to 74% + 3 months free
  • Stops intrusive ads before they can even load, improving browsing experience and speed
  • Identifies malware-ridden files and protects against visiting malicious websites
  • Encrypts your data and blocks third-party trackers for increased security and privacy
  • Lacks a dedicated firewall

NordVPN Threat Protection is an integrated ad and malware blocker included with NordVPN, one of the best virtual private networks on the market. But its plans come with a lot more than just the ability to encrypt your internet connection. You can use it to block ads, trackers, and malicious websites, and to scan downloaded files for malware. 

You can also opt to use Threat Protection Lite while connected to NordVPN, ensuring that your device is protected from pesky ads and malicious sites whenever you need.

What we liked

NordVPN Threat Protection had some impressive test results when we were testing for AdBlock Tester and Cover Your Tracks. It received a 93/100 score for ad blocking, a near-perfect score, and 2/3 for tracker blocking, showing that it can block tracking ads and invisible trackers. It also allows for whitelisting and blacklisting, so you can tailor your ad-blocking experience as needed.

We also like that Threat Protection can block malware, too. Threat Protection passed our malware detection and phishing detection tests, so we felt reassured that NordVPN could act as a well-rounded cybersecurity suite. Like other Nord products, Threat Protection was easy to set up, and its interface was intuitive.

What we didn’t like

NordVPN Threat Protection can be pricey, considering you're paying for a VPN subscription and not just a premium ad blocker. Surfshark has its own ad and malware blocker, known as CleanWeb, that's more affordable. (Learn more about CleanWeb below.)

If you opt to use Threat Protection Lite, the capabilities are pretty limited. Threat Protection Lite can't block trackers or scan for malware, which could put your device in danger of malware if you're not using an antivirus program. 

NordVPN Threat Protection: pros and cons

Pros
  • Blocks ads, trackers, and malware
  • Allows for whitelisting and blacklisting
Cons
  • There are cheaper alternatives in the market, like Surfshark CleanWeb
  • Threat Protection Lite is limited

Surfshark CleanWeb: Best for affordable privacy

Comprehensive Ad Blocking Online and in Apps + VPN Connection

Ad Blocker
Surfshark CleanWeb Ad Blocking
86% off + 3 months free
  • Blocks ads, banners, and pop-ups on your browser and apps, including smart TVs
  • Enjoy boosted browsing speeds and save money on mobile data with its effective ad-blocking capabilities
  • Added benefit of a VPN to encrypt your data, hide your IP address, avoid phishing scams, and minimize malware risks
  • Does not completely hide your digital fingerprint

Similar to NordVPN Threat Protection, Surfshark CleanWeb comes included with Surfshark VPN, both of which are key tools of the Surfshark One cybersecurity suite. By hitting a toggle on your VPN settings, you can block ads and pop-ups, autoplay video ads, cookie pop-up requests, and more. 

Surfshark also provides CleanWeb 2.0, which is included with the Surfshark browser extension for Firefox, Google Chrome, and Microsoft Edge. CleanWeb 2.0's capabilities include blocking ads and cookie pop-up banners and receiving alerts for data breaches and malware.

What we liked

We were pleased to see CleanWeb receive a perfect ad-blocking test score. It also received a 2/3 Cover Your Tracks score, so you can be largely protected from ads and trackers online. 

We also like that you can get CleanWeb for a cheaper cost than its competitor, Threat Protection. Surfshark's pricing starts at $2.19/mo (billed every two years) for a two-year plan (often with some extra months thrown in), and it allows for unlimited simultaneous connections so you can encrypt your internet connection and block ads on multiple devices. It also offers a 30-day money-back guarantee, so you can try it out for a month

What we didn’t like

Although Surfshark is an affordable ad blocker, you'd still be required to buy a VPN subscription in order to use Surfshark CleanWeb. This may not be ideal if you already have a VPN or if you're just looking for an ad blocker. 

In addition, you can only access CleanWeb 2.0 with the Surfshark browser extension. This can be frustrating if you're trying to block ads on your smartphone or other devices. 

Surfshark CleanWeb: pros and cons

Pros
  • Perfectly ad-blocking test score
  • CleanWeb 2.0 blocks all ads, including YouTube ads
Cons
  • Surfshark subscription needed
  • CleanWeb 2.0 only available as a browser extension

uBlock Origin: Best for unique add-ons

Ad Blocker
uBlock Origin
  • One of the best totally free ad blockers available
  • Highly customizable, open-source ad blocker that's compatible with multiple browsers
  • Can block advertising and analytics tools, including banner ads, video ads, and trackers, and can even bypass soft paywalls
  • Better suited for advanced users because some features require technical knowledge

uBlock Origin is open source software that's available on a variety of browsers and offers the most customizable features of any other brand we tested. Along with the basic services of blocking ads, trackers, and malicious URLs, this ad blocker includes several more customizable features that may keep you safe during your web browsing.

Firefox’s website for the uBlock Origin extension calls it “a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.”

Related to the company’s mantra, a user’s personal study on GitHub highlighted that uBlock Origin uses less computer memory than some of the leading brands.[1] The benefits of reducing memory consumption include speed and page stability, so you can use this ad blocker without worrying about sacrificing your PC’s memory data.

What we liked

uBlock Origin scored 96/100 with AdBlock Tester, and the tests it didn't pass were listed as "test has most likely passed." We initially had some issues with Cover Your Tracks, but after some tinkering, we received a 2/3 test score. 

We also liked that the extension offers a multitude of filter lists that you can enable or disable within your settings. These lists are additional options beyond their default settings, such as:

  • EasyList Cookie: Blocks cookies banners, GDPR overlay windows, and other privacy-related notices 
  • Fanboy Annoyances: Blocks social media content, pop-ups, and other annoying objects to help decrease webpage load times
  • AdGuard Annoyances: Blocks cookie notifications, pop-ups, mobile app banners, widgets, and other annoyances
  • Dan Pollock’s hosts file: Stops your PC from connecting to certain internet hosts to protect you from spyware and pop-up traps, prevent further tracking, and reduce bandwidth use

What we didn’t like

uBlock Origin released its JavaScript blocking feature in September 2018, taking the extension a step forward in blocking Javascript that can hide malware or attempt exploits. While this was a positive step for the organization, some recent user reviews from the Firefox browser extension showed concern about the feature automatically blocking certain websites. Luckily, the developer addressed the issue by fixing it in GitHub and responding directly to the review.

Another potential misstep for uBlock Origin is the lack of a support website or contact form for user issues. After searching its main webpage, we found that you can reach them through an email address at the bottom of the page that will populate if you click “get in touch.”

uBlock Origin pros and cons

Pros
  • Software doesn’t use as much PC memory
  • Offers customizable add-on features
Cons
  • Scripting block feature may block content from wanted websites
  • No support website

Honorable mentions

There are plenty of ad blockers on the market for you to consider. Here are some tested alternatives (which also unblock YouTube ads):

  • Adblock Plus: Adblock Plus states that it blocks all ads by default, including YouTube ads. You can also customize which sites allow ads and view how many ads you’ve blocked.

    Read Our Adblock Plus Review

  • AdGuard: AdGuard blocks ads and trackers and provides many filter options to create a seamless and safe browsing experience. It offers custom filters in several languages, so you can block unwanted ads from websites worldwide. This software has a filter specifically for social media, which is a great idea since cybercriminals love to use social media as an exploitative resource.

How we tested the best ad blockers for Firefox

We tested the most important security components for each ad blocker before choosing our top four best ad blockers for Firefox. First, we tested the ad blockers through AdBlock Tester, a site that permits you to test your ad blocker against analytics and advertising services embedded within the testing website.

Next, we tested the ad blocker through Cover Your Tracks, a website that reveals how trackers view a browser. We used the site to test whether the ad blocker was truly blocking tracking ads and invisible trackers. Knowing how important it is for you to bypass social media and video ads, testing the ad blockers on YouTube was the third and final component of our testing process.

To ensure that each testing experience was unique, we fully disabled each ad blocker browser extension before enabling the next ad blocker on our list. Additionally, we made our top three selections because they had top scores in blocking ads, blocking trackers, and blocking ads that live on social media, among other factors.
