Ads are one of the biggest annoyances that you will come across while surfing the internet. Websites place ad banners, and when visitors view the ads or interact with them, it earns the site revenue.  Nearly every website has ads, even big ones like Facebook, Twitter, Reddit, YouTube, etc.  Why?

uBlock Origin

uBlock Origin main features & specifications summary

• Rating: 5/5

uBlock Origin pros & cons

Pros

• Protects you from being tracked by advertisements
• Disables ad banners without leaving blank spaces
• Saves data by blocking ads
• Many user lists that you can subscribe to block various ads, trackers
• Custom filters to block elements on websites
• Pages load faster
• Open Source
• Light on resources

Cons

• Slightly complex interface compared to AdGuard
• Does not prevent affiliate URLs from tracking you.
• You may have to toggle the add-on, or purge the cache if web pages aren’t rendering properly, e.g. if a web page’s menu is not working.

When you visit a web page or perform a search query, your browser stores some information about it in the form of a cookie. Many sites use this data, i.e. to find what you like, products you may be interested in, to display advertisements that are relevant to your online activity, aka targeted ads. So if you searched about cars or televisions, you will see ad banners about these on many sites that you visit.

This can be annoying to see, and your browsing habits are also tracked by the ad server. That is creepy and dangerous. Some web services have come under scrutiny for harvesting user data, and even selling them to third-parties. uBlock Origin blocks the ads automatically, allowing a greater control over your privacy.

Many good articles often look terrible, because the site placed an ad after every paragraph or on the sides. Just imagine how nice the page could look, if there weren’t any of these annoyances. uBlock Origin gives you a cleaner version of web pages, that is devoid of distractions, trackers and malicious scripts, without breaking the site. You don't even need a separate pop up blocker for Chrome.

If you watch videos on YouTube, you may have noticed that some of them start with an ad, that is usually skippable after a certain amount of seconds.. These can ruin the experience, sometimes can be really loud or just plain annoying or irrelevant. You can avoid video ads with uBlock Origin, and you don’t even need to set it up to do this, the extension blocks all these ads right out of the box.

But all things said, uBlock Origin is more than an ad-blocker, it is a spectrum wide content blocker. What that means is that it can be used to block Javascript from running, which further reduces the amount of trackers that try to obtain your personal data. Besides you can also use it to manually block content on websites, using the Element Picker. These advanced features make other add-ons like noScript, Privacy Badger, and the like, redundant.

uBlock Origin uses filter lists maintained by volunteers, this is how the plugin detects requests to ad servers, and blocks them before a web page is loaded. In addition to this, there are loads of optional filter lists that you can select, to improve the ad detection and blocking rate.

Have you ever run into a site that asks you to disable your ad blocker, well you shouldn’t disable the extension. Instead, go to uBlock Origin’s settings, and toggle the annoyance filter list, this will block the anti-adblock script that the web page uses. This way your privacy isn’t compromised, and you can access the content, just like the way the free internet is meant to be.

Try visiting a web page without an ad-blocker, and then once again this time with uBlock Origin installed. You’ll literally feel the difference, without the plugin, the sites will open slower and your computer also uses more resources to load the page. With the ad blocker installed, the number of elements that are needed to be loaded are reduced, which in turn results in pages being rendered faster, and the load on the system performance is lighter too. Take some time to read the extension’s documentation, learn how to use the advanced options, and you will have a really powerful content blocker at your disposal.

AdGuard AdBlocker

AdGuard AdBlocker main features & specifications summary

• Rating: 4/5
• Browser compatibility: Chrome, Firefox, Safari & Brave
• Pricing: Free (open source)
• Features: Ad blocking, Removes Social Widgets, Prevents Trackers

Pros

• User-friendly interface
• Open Source
• Has its own filter lists
• Supports third-party filters
• Removes Social Media Widgets
• Can block specific elements on web pages
• Does not impact the browser or system performance

Cons

• Advanced options take some time getting used to
• On rare occasions, can prevent sites from loading correctly

AdGuard AdBlocker is the second best ad blocker extension for Chrome, in my opinion. This add-on is made by a company called AdGuard. For those unaware, the company’s main product is a desktop program that blocks ads system-wide in Windows, and it’s a premium software. The browser extension, AdGuard AdBlocker is free and open source. You don’t need to sign up for an account, or pay a penny to use it.

The add-on’s interface looks pretty and its setting page is much more appealing compared to its rival, uBlock Origin. This makes AdGuard AdBlocker somewhat easier to use, and it works pretty much efficiently without having to set it up.

Another cool thing about the plugin is that it supports uBlock Origin filters, and similarly, you can use AdGuard’s filters in uBO. You may also import custom filters from third-party sources. AdGuard is consistent in preventing all kinds of ads, it can block ad banners, pop up ads, video ads, etc.

In my article about Firefox Containers, I explained how social media sites can track you around the web. A lot of websites have social media buttons on their pages, which makes it easy for you to contact them. The problem here is that these aren’t merely buttons, they can be used to track your visit to the page.

Facebook Pixel is perhaps the most notorious of the lot, but I digress. AdGuard AdBlocker has a Social Widgets option, which when enabled will remove the buttons from Facebook, Twitter, Instagram, etc, thus preventing them from tracking and profiling your browsing patterns.

AdGuard’s Chrome extension has an element picker mode, for selecting specific parts of a web page and blocking them. The Security Filters are quite good, and can block sites which are known to mine cryptocurrency, uBlock Origin can block these too. The stealth mode in AdGuard is something that advanced users maybe interested in. It helps prevent trackers from profiling you., send do not track requests to websites, blocks WebRTC and can even filter tracking elements from URLs.

AdGuard AdBlocker has a whitelist mode which is useful for allowing ads on specific websites. And you have User Rules for customizing the ad blocking behavior. The add-on allows search ads by default, which is something I’m not a fan of, so I recommend disabling this option from the settings, in order to prevent products and appearing at the top of the search results page, otherwise the search provider can use the data to track you.

AdGuard DNS is a free service that the company offers, you can use it on Windows, macOS, iOS and Android devices to block ads system-wide. I use it on my Android phone and iPad to block ads in apps.

We have an in-depth review highlighting the features of AdGuard, which you may find helpful.

SponsorBlock - Skip Sponsorships on YouTube

SponsorBlock main features & specifications summary

• Rating: 4/5
• Browser compatibility: Chrome, Firefox, Safari & Brave
• Pricing: Free (open source)
• Features: Skips sponsored segments in YouTube videos

Pros

• Crowd-sourced
• Easy to use
• Open source

Cons

• Not a standalone ad blocker

Website ads aren’t the only way companies advertise their products and services, many companies partner with YouTube content creators to promote their products. You may have noticed this in videos, where a sponsorship message is played for a few seconds.

Now even though these are ads, they’re not going to be picked up by normal ad blockers, since they are actually part of the video. But there is a way to avoid these sponsored segments, with the help of the SponsorBlock extension.

The add-on uses a crowdsourced database, i.e., users who have the extension mark/report the time stamps of sponsored segments in a video. This data is stored in the online database, and the next time a user who has installed SponsorBlock plays the video, the extension will automatically skip the part that was reported by the other user, thus saving you some time. Since it is crowd-powered, you can report promotional sections in videos too, and help other users. But this is not mandatory.

Install the extension and you will see a shield icon appear in the YouTube playback bar. This indicates that the add-on is working, mouse over the icon and a few more icons will be displayed. Click on the icon to the left and you will see a pop-up detailing the number of sponsored segments in the current video.

The extension also displays the segments in the timeline (seek bar) of the video. But, you don’t need to click anything for SponsorBlock to work. Once the video reaches the timestamp that has been marked as a “sponsored segment”, it skips the section and continues playing the video. You can undo the skip, if you’re quick enough, by clicking the option that appears on the screen.

SponsorBlock is customizable and can be used to skip intros, outros, and is easy to configure.  You may whitelist channels if you wish to support them by watching the sponsored content. The main drawback of the add-on is that it is not a standalone ad blocker extension, meaning it will be unable to prevent regular ads from playing. So, SponsorBlock is best used as a companion extension alongside uBlock Origin or AdGuard AdBlocker.

Don’t forget to read our SponsorBlock review to learn more about the plugin.

uMatrix

uMatrix main features & specifications summary

• Rating: 4/5
• Browser compatibility: Chrome, Firefox, Safari & Brave
• Pricing: Free (open source)
• Features: Advanced script blocker, customizable

Pros

• Greatly enhances the protection of the browser
• Open Source

Cons

• Not user-friendly, has a steep learning curve
• uMatrix is no longer actively developed, but the add-on still works

If you like uBlock Origin, but want more granular control, uMatrix is the perfect solution. Both extensions are made by the same developer. I would recommend using one or the other as they essentially serve the same purpose.

The ad blocker, in its default settings, is meant to prevent ads without any intervention from the user, something which it excels in. uMatrix on the other hand focuses on script blocking, which can prevent malicious scripts much more effectively, you can basically block everything and only allow the ones you choose. In a way, it’s even better than uBlock Origin’s Dynamic filtering. The problem is you’re probably going to spend a lot of time un-breaking sites, which kind of makes it a pain to use. You could opt for the allow all mode, and block sites specifically, but it’s sort of counter-productive.

Load a web page and then click on uMatrix’s button, and you can choose to block elements on the site like specific cookies, images. Click on the content that you want to block, and use the logger to monitor the elements, and unblock them as necessary.

uMatrix is meant for advanced users, so if you’re a novice or an average user, stick to uBlock Origin. The latter can also be set to block scripts in medium and hard mode, which is what I recommend if you want a less complicated way to block web scripts from running.

Our uMatrix review has all the details you need to get started with the add-on.

List of popular Chrome extensions that didn't make the cut

NoScript Security Suite

Pros

• Free (Open Source)
• Only allow scripts from trusted sites to run
• Blocks scripts from running
• Protects you from malicious scripts

Cons

• Has a learning curve
• Can cause issues on banking sites, payment gateways

If you are paranoid about online security, NoScript is definitely worth checking out. The internet relies on scripts to run, especially javascript. The problem is, web pages can contain malicious scripts which can infect your browser or redirect it to other harmful pages. The NoScript add-on blocks scripts globally. You may add specific websites to the whitelist, allowing scripts from those pages to run, while blocking the rest.

Why is NoScript not included in our recommended Chrome Security extensions?

uBlock Origin and uMatrix offer script blocking as well, so you don't need an extra one in NoScript. While NoScript is a complicated extension, it's a bit easier to get used to than uBlock's script blocking. Script blocking has its own issues, and with NoScript you may have problems shopping onlint. The extension may prevent scripts from running on checkout pages and payment gateways, causing your online transactions to fail.

Privacy Badger

Pros

• Free (Open Source)
• Blocks ads, canvas based fingerprinting
• Relies on its Badger-Sett, a pre-trained list to block trackers
• Does not block all ads

Cons

• Learning mode is disabled by default, as it can be used to fingerprint users

Privacy Badger is a nifty little extension to have in your security extension toolbox. The add-on does a good job of blocking ads, and has its own filter, just like a normal ad-blocker. The yellowlist is used for blocking tracking cookies on sites, and the extension also prevents canvas based fingerprinting.

Why Privacy Badger did not make it to our list of recommended Chrome Security extensions?

Privacy Badger’s advanced learning aka local learning, is turned off by default. The EFF in its own words explained that local learning creates a unique fingerprint which can be used to identify the user. The anti-tracking extension has been toned to being an ad-blocker, and is now reliant on its Badger-Sett. This is something that uBlock Origin can handle, and more.

AdBlock Plus

Pros

• Free (Open Source)
• Good at blocking most ads
• Easy to use

Cons

• Acceptable Ads enabled by default, can be disabled
• Unethical practices
• Inconsistent ad blocking, gets detected by anti ad block scripts
• Higher system resource usage

AdBlock Plus is one of the most popular ad blocker created for browsers. It blocks ads on most websites, unless you opt out of the acceptable ads initiative, in which case it displays non-intrusive ads.

Why AdBlock Plus was not included in our list of best ad blockers for Chrome?

The developer of AdBlock Plus decided to partner with websites and ad companies, to create acceptable ads, a whitelist that allows ads to be displayed. The idea was to support websites, but in reality the partnership brings money for the extension’s developer, while the user’s privacy is compromised. This is one of the cases where the saying “if something is free, then you are the product” is literally true.

That is an unacceptable compromise, but even if you brush off the ethical part here, AdBlock Plus has some inconsistencies in blocking ads, and seems to get detected by anti-adblock scripts.  It tends to load pages slower, and uses more resources compared to uBlock Origin, and even AdGuard for that matter.

AdBlock

Pros

• Free (Open Source)
• Decent ad blocker

Cons

• Unethical practices
• Participates in the Acceptable Ads program
• Not as good as uBlock Origin

AdBlock is an extension that prevents ads on most sites, including Facebook and YouTube. Its performance on the other-hand is sub-par compared to the better ones.

Why wasn’t AdBlock picked as one of our top recommendations?

AdBlock’s story is nearly identical to AdBlock Plus. AdBlock was sold, and then joined in the controversial Acceptable Ads program. AdBlock acquired uBlock, and the changes that were introduced to the latter forced the original developer to create what is now known the best ad blocker ever made, uBlock Origin.

Ghostery

• Pros
• Free  (open source)
• Easy to use

Cons

• Unethical practices in the past
• Questionable privacy policy
• Not user-friendly

Ghostery is an ad blocker that prevents ads, and stops websites from tracking you. The extension is fairly simple to use.

Why Ghostery is not among our recommended list of Chrome ad blockers?

Ghostery has a shady past. The add-on was found to collect information about ads that were blocked and sent the data to its servers, which was then shared with advertisers. The extension was eventually made open source in what appeared to be a move to win the trust of users. Ghostery’s privacy policy states that the company collects data such as the web browser, operating system, language, non-private URLs, search queries along with search engine results pages, among other telemetry.

Frequently asked questions about ad blocker extensions for Chrome

My ad blocker isn’t blocking ads correctly, but another one does, which one should I use?

If a different add-on works for you, that’s good. But I have been using uBlock Origin ever since the first release and it has been nearly flawless. On the off chance it fails to block some ad, try purging the cache and update the filter lists from the extension’s settings. If you want to block a specific part of a web page, you should use the Element Picker tool to create a filter for it manually. Never use multiple content blockers, because they are going to interfere with each other’s rules and filters, and you could experience some issues with web pages, and the performance of the browser and computer.

I still see ads on YouTube, what should I do?

While I have not seen this happen with uBlock Origin installed in Firefox, this has been a common problem in Chromium based browsers, especially Brave and Opera, with their built-in ad blocker enabled. The browsers struggled with what appears to be a new method for YouTube to deliver ads, though the issue seems to have been fixed in recent updates.

Why haven’t you included AdBlock Plus in your list?

AdBlock Plus allows acceptable ads. Basically, the developer has partnered with ad networks and websites to allow some ads to pass through the extension’s ad filters in exchange for monetary compensation. This move has been widely criticized among security experts, as it exposes users to ads and trackers. There is an option to disable acceptable ads, but due to ethical reasons, we cannot recommend you use the extension.

On a side note, we do not recommend using AdBlocker Ultimate, as it is a clone of the AdGuard extension. And while we are at it, don’t use the add-on that’s just called uBlock, the good extension is called uBlock Origin. There are a lot of adblock extensions for Chrome which have privacy issues, avoid those and choose one of our suggestions, all of which are open source, and made by ethical developers.

Will adblockers stop working on Chrome with Manifest V3 API?

You may not be aware of this, but Manifest V3 is already in use. The important thing here is that V2 still exists which is why older extensions work fine, including adblockers. Manifest V3 has drawn the ire of Chrome’s rivals such as Mozilla, Brave, Vivaldi, and their browsers will continue to support ad-blockers in their own implementation.

The Manifest V3 API is still in an early phase, and is being worked on by Google. uBlock Origin’s creator, Raymond Hill, aka gorhill, recently said that he is working on a version of his extension that supports the new API. Thanks to some changes made to the declarativeNetRequest API, the adblocker could retain dynamic filtering, important filter, etc. Even he doesn’t know which features could break if V2 is discontinued in favor of Manifest V3. So, don’t panic yet, there is hope. In the worst case scenario, we will still be able to block ads system wide by editing the hosts file, or by using a DNS.

Bottom line/Conclusion

uBlock Origin is our number one choice when it comes to ad blocking, though AdGuard isn’t far behind. Regardless of which ad blocker you use, I recommend using SponsorBlock with it for the best possible ad blocking experience. All extensions mentioned in this article are available for Firefox and Chrome.
