How we test and rate ad blockers

Each ad blocker we review goes through a standardized test designed to push the limits of what the software is capable of. This includes vigorous third-party testing using websites like,, and We also visit popular websites to test the ad blocker’s day-to-day capabilities, including watching YouTube videos and browsing Forbes.

Once we’ve completed the testing, we calculate our editorial rating by taking into account key features you’d expect from a good product. We score each ad blocker in the following categories and use a weighted average to calculate the final rating out of 5 stars:

  • Price
  • Test scores
  • Features
  • Browser support
  • Editorial score

Our experience

AdLock’s website isn’t too fancy or overly sales-y. It took a little poking around before we found out we had to install the browser extension if we wanted to test the free product. This was after clicking around on download links trying to find out which product was best for us. Maybe a little more sales language would have helped.

Also, when we clicked the Windows download, we got a 404 message. This is probably because we hadn’t purchased a license yet.

Once we installed the extension, it was pretty fun to test. We went to YouTube first, then pulled up some popular blogs. Below, the window on the left is Microsoft Edge running without AdLock and the window on the right is Chrome running with AdLock. Notice the difference in ads.

The Edge browser had an ad just below the featured recipes, while the Chrome browser with AdLock took us straight to the featured video. Since The Pioneer Woman’s website didn’t have video follow-along ads, we went to a site that does.

A side-by-side comparison of a recipe page with AdLock on and without AdLock on.

Sam Turnbull’s popular vegan recipe site, It Doesn’t Taste Like Chicken, is less cluttered with ads than other recipe blogs, but still has follow-along videos that chased us down the page on our Edge browser. Notice how they aren’t there on Chrome, which was protected with AdLock. (In fact, AdLock is one of the best ad blockers for Chrome.)

The only feature that didn’t really work for us was pop-up blocking. This may have been because they were newsletter follow requests, but AdLock’s homepage says it blocks pop-ups. You can see we received the newsletter request on both browsers — Edge, which wasn’t running AdLock, and Chrome, which was running it. 

While this may not be the biggest issue, phishing attempts, malware, and general online privacy concerns can all be an issue when entering your information into the wrong pop-up.

The good part is that the banner ad present in the Edge browser wasn’t there in the Chrome browser. So while we were hijacked for a second by the newsletter pop-up, AdLock still worked on removing the banner ad.

AdLock paid plan

AdLock offers free browser extensions for Safari, Firefox and Chrome, but all the other accessibility options are through paid plans. 

The payment options are monthly, yearly, or five devices for five years. This plan is particularly useful if you have multiple computers and mobile devices you’d like to protect. 

  • 1 month/5 devices: $3.50/mo
  • 1 year/5 devices: $2.80/mo
  • 5 years/5 devices: $1.05/mo

Overall, the yearly and five-year plans have the most value and are definitely worthwhile considering the extra protection you’re receiving.

The free plan can block ads, but not all ads and it can't block ads in apps either.

The paid plans promise no forced whitelisting, no tracking, a 30-day money-back guarantee, and 24/7 support. All payment options include the same features and are only different depending on what type of subscription you want.

AdLock only accepts Visa, Mastercard, and PayPal; it has no options for other forms of payment like other credit card issuers and cryptocurrency.

AdLock offers a 14-day free trial and a 30-day money-back guarantee. To receive your refund, you'll need to contact AdLock via email (

Main features

Like most ad blockers, AdLock has features to block ads and trackers. It also has unique features like filters for languages and social media widgets. 

We'll break down AdLock's features below.

Ad blocker

AdLock’s browser extension gave us an easy view of what ads were blocked on the individual webpage and how many have been blocked overall. 

The Forbes homepage along with the AdLock browser extension indicating that 7 ads were blocked on the page.

But unlike other products, AdLock functions only within your system, which means it isn’t outsourcing your requests. You can easily toggle the ad-blocking software off or on depending on the site you’re visiting. 

If you open the app, AdLock will also list out the number of blocked requests and the amount of saved traffic from using the app. For more details, you can click through the Ads reports tab, which breaks down ads blocked by app and domain, or Adblocking statistics, which provide detailed information on blocked commercial content.

On the app you'll find the Protection tab, which is where you can keep taps on AdLock's anti-tracking and anti-phishing features.

AdLock can hide your online presence and personal data from advertisers as well as protect you from phishing, scammers, and malware. All you need to do is turn the toggles on from this tab. 

You can also select Protection statistics for detailed information on blocked trackers, suspicious requests, and intrusion attempts.

Ad filters

If you go to AdLock's settings, you'll find a list of filters for various purposes. There's a spyware filter to help stop websites from tracking your activity, a social media filter to protect your from social media tracking, and annoyances filter to block site elements like online chats and notifications.

AdLock also provides filters for multiple languages to block ads on international websites.

Many languages are available for universal browsing.

Unfortunately, the spyware filter and social media filter are only included with the paid tier.


With allowlist, you can distinguish that your favorite creator sites or other sites should run only without an ad blocker. This is also known as whitelisting. 

The AdLock user allow list feature.

A whitelist or a filter list allows you to visit your favorite creators or sites without altering permissions each time.

If you want to make sure your favorite creators get credit for their work, you can easily toggle off the blocker so they receive the ad revenue.

AdLock's test results

A product can tell you all day it’s good, but is it actually? Third-party sites like AdBlock Tester, Cover Your Tracks, and Can You Block It? put those claims to the test.

Adblock Tester checks a variety of different ways that ads can be displayed to see how your ad blocker performs. Overall, the AdLock app and browser extension did pretty well with blocking ads. It only failed the sentry tests, which are used to track and measure errors on websites, so it's only a minor issue.

Test results as of 04/17/2024.

Cover Your Tracks checks tracking ads and your digital fingerprint to see if you’re browsing anonymously. The more unique your fingerprint, the easier it is to connect information from tracking ads to you. 

AdLock was successful at blocking tracking ads and invisible trackers. Our fingerprint was listed as nearly-unique, so it wasn't a perfect score, but we've found that most of the ad blockers we test score similarly.

Finally, Can You Block It? tests ad blockers against self-hosted ads, including banner ads, interstitial ads, and ad blocker detection warnings. AdLock could only block banner ads and ad blocker detection warnings, though.

The interstitial ad appeared, but AdLock blocked the content of the ad, so it was just a blank page with text. We're glad AdLock blocked the bulk of the ad but were annoyed we still had to deal with it rather than going straight to the pge.

YouTube ad test

AdLock blocked YouTube ads seamlessly and with no lag. We tested this by watching a video from Enes Yilmazer’s popular real estate channel, which is always inundated with ads. 

The nearly 20-minute video never tried to load video ads before or during viewing, and there were no page-loading issues. AdLock even gave us a breakdown of how many ads it blocked on the site.

Just remember that channels like Yilmazer’s run ads specifically to pay the creator for their time and effort. If you have favorite content creators, disabling your ad blocker will allow them to receive revenue from ads. A lot of work goes into content creation, so choosing to see a few ads in return for the value you receive is definitely worth it.

Bypassing paywalls test

We're on the hunt to find an ad blocker that can tackle paywalls. It can be frustrating when an article grabs your attention, only to be blocked from reading it when you click through.

Unfortunately, AdLock doesn't include bypassing paywalls with its arsenal of features. We checked The Wall Street Journal, Bloomberg, and The Atlantic, but all three sites prompted us to sign up for a subscription.

What browser and software is it compatible with?

AdLock has two different types of products. The first is the free version for Chrome, Firefox, and Safari browsers, which block ads when you're using your browser. The second is a paid version for operating systems. The paid version increases privacy across your machine. But don’t sleep on the free browser extension; it’s pretty powerful, proven by our test results.

The ad-blocking apps can be found in the Apple App Store or at the links below.

Browser extensions/add-ons:

  • Google Chrome
  • Safari
  • Mozilla Firefox

Operating system apps:

  • Android
  • iOS
  • Windows
  • macOS

AdLock privacy policy

Reviewing the privacy policy for products you use is important to make sure your data isn't shared or sold. We were pleased that AdLock "doesn't sell or share [usage information] with third parties."

It mentions collecting anonymous usage information, like browser language and number of blocked ad requests, but it's not sold or shared with third parties. All AdLock extension users will receive a unique ID that's assigned anonymously upon installation. It'll be stored on AdLock's servers until you uninstall the extension from your device.

The privacy policy also breaks down how your data is used by third parties for analytics, handling payments, hosting and backend infrastructure, and other uses. Although your email may be used for promotional and informational purposes, you do have the option to opt out.

Overall, we liked how easy to read AdLock's privacy policy is and we feel good about its data usage. 

How to use AdLock

To set up AdLock, you'll need to decide if you wish to use the AdLock app or browser extension (or both). Once you've selected your preferred software, you can visit the AdLock site to download.

AdLock FAQs


Is AdLock free to use?

AdLock offers free browser extensions for Chrome and Safari. Products for Windows, macOS, Android, and iPhone all require subscriptions outside of the browser extension.


Is it safe to download AdLock?

Yes, it's safe to download AdLock's browser extension and app. Just be sure to download it from the AdLock website or your browser's official extension site.


Does AdLock sell your data?

By all accounts, it doesn’t look like AdLock sells your data. Its privacy policy states that data is collected for usage purposes and not sold to third parties. The policy goes on to break down third-party connections, what data they collect, and what it’s used for.


What are the pros and cons of AdLock?

AdLock’s pros include free browser extensions for Safari and Chrome, no data sales to third parties, transparent privacy policies, and strong ad-blocking technology. There aren’t many cons, but you do have to pay for the social media blocker and its payment options are limited.

Bottom line: Is AdLock a good ad blocker?

AdLock really is a good ad blocker. Not only does it block out most ads with just the free browser extension, but it also respects your privacy. 

If you want increased protection, such as from data-mining social media sites, AdLock has you covered with its paid tier. While we still got a pop-up or two, AdLock really delivered on its promise.

AdLock is definitely worth your time and maybe even your money. This is one of those products that’s so good, we’ve considered paying for it. If you’ve been shopping for a powerful ad blocker that delivers without sacrificing your data, we suggest giving it a try.
