uBlock Origin - Free, open-source ad content blocker.
Easy on cpu and memory..
uBlock Origin is not just an “ad blocker“, it's a wide-spectrum content blocker with CPU and memory efficiency as a primary feature.
Open-source ad blocker
The uBlock Origin is a free and open-source, cross-platform browser extension for content filtering—primarily aimed at neutralizing privacy invasion in an efficient, user-friendly method.
CPU and memory efficiency
Globally, uBlock Origin could save consumers more than $1.8 billion/year( study ). Open source ad blockers are a potentially effective technology for energy conservation.
Various browsers support
uBlock Origin’s extension is available for several of the most widely used browsers, including: Chrome, Chromium, MS Edge, Opera, Firefox and all Safari releases prior to 13.
About uBlock Origin
In 2014 uBlock Origin’s founder, original author and lead developer, Raymond Hill, created the original uBlock extension, with its development initiated by forking the codebase of HTTP Switchboard with a separate blocking extension, uMatrix, which had been previously designed for advanced users. The initial uBlock was developed by Raymond Hill in order to enable community-maintained block lists while simultaneously adding additional features and upgrading the code quality to proper release standards. First released in June 2014 as an exclusive Chrome and Opera extension, in late 2015 the initial uBlock extension expanded to other browsers under its current name – uBlock Origin. (occasionally represented globally as – uBlock₀).
Following this 2015 introduction, a collaborative comsource and Sourcepoint industry research survey reported an 833% growth rate over a 10-month period ending in August 2016, the most rapid growth among any industry software publicly listed at that time. This report attributed this enormous surge to collective user demand for “pure” blockers with the capacity to operate outside the “acceptable advertising” program used by AdBlock, and other industry extensions.
Quickly gaining traction throughout the entire ad-blocking industry, the uBlock Origin Firefox version collected over 5 million active users, with its Chrome extension subsequently compiling over 10 million active users. Developer Nik Rolls then officially released uBlock Origin for the Microsoft Edge browser in December 2016.
In January 2017, uBlock Origin was added to the repositories for Debian 9 , and Ubuntu (16.04), and the uBlock Origin extension was awarded the prestigious IoT honor of “Pick of the Month” by Mozilla.
As of 2024, uBlock Origin continues to be maintained and actively developed by founder and lead developer Raymond Hill.
The uBlock Origin extension remains an industry leading, open-source, cross-platform browser extension with software developed specifically for multiple platform use, and as of 2024, uBlock Origin’s extension is available for several of the most widely used browsers, including: Chrome, Chromium, Edge, Opera, Firefox and all Safari releases prior to 13.
The uBlock Origin project still specifically refuses donations at this time, and instead advises all of its clients, users and supporters to donate to block list maintainers.
Finally, an efficient blocker. Easy on CPU and memory.

The best ad blockers in 2024
Say goodbye to irritating ads, thanks to the best ad blockers
Best in-browser ad blockers
Best ad-blocking apps, best ad-blocking mobile apps, other privacy-focused extensions and apps.
The best ad blockers are incredibly important tools, and the start of the new year is a good a time as any to start taking advantage. It almost feels like it's impossible to browse the web without being harassed by pop-ups, malvertising, tracker cookies and all sorts of nasty and intrusive things. Even if the content is all above board, those bad ads could appear anytime and anyplace.
Thankfully there's no shortage of browser extensions and apps that can keep you safe. Blocking ads and all the other irrelevant stuff that you may encounter. Combined with the best antivirus software and the best VPNs , it gives you a perfect arsenel of tools to ensure you have as much protection as possible. Even the FBI recommends using an ad-blocker for protection.
The only thing you need to figure out is which ad-blocker is right for you. There are so many to choose from, and whether you are willing to live with the downsides. Most free sites rely on advertising revenue to survive, including Tom's Guide. But if you're happy with the trade-off, we've got a thorough list of the best ad blockers and privacy tools — with options for every browser and platform.
The best ad blockers you can get today
1. adblock plus (chrome, edge, firefox, opera, safari, android, ios).
AdBlock Plus (ABP) is among the most popular ad blockers, with extensions available for Firefox, Chrome, Safari, Edge and Opera. ABP features a quick setup, loading preset filter lists that allow users to quickly block most ads, as well as the option to filter malware and social media buttons.
Savvy users can chose additional block lists as well as set custom filters or whitelist their favorite sites to keep their ad revenue in the black. AdBlock Plus allows what it calls "non-intrusive advertising" through filters; that may irk some users, though this feature can be disabled in settings.
On Android, the AdBlock Browser provides a Firefox-based browser that blocks incoming advertising, while on iOS, the AdBlock Plus app integrates with the content blocker system to seamlessly block advertising on Safari with minimal setup.
Download AdBlock Plus: Firefox , Chrome , Safari , Opera , Edge
2. AdBlock (Chrome, Firefox, Safari, Edge)
AdBlock (no relation to AdBlock Plus) is the other best ad-blocking browser extension of note, available for users of Chrome, Firefox, Edge and Safari. AdBlock uses a series of filter lists to automatically block ad content coming from known ad servers and providers. Users can stick with the default block lists, subscribe to additional ones, or even create their own, as well as whitelist their favorite websites.
As one of the most downloaded Chrome and Safari extensions, AdBlock has the trust of many users worldwide.
Download AdBlock: Chrome , Firefox , Safari , Edge
3. uBlock Origin (Chrome, Firefox)
Ublock Origin is a browser-based ad blocker that focuses on simple, efficient blocking with a low resource overhead. The extension comes loaded with a number of filter lists for known advertising and malware sources, with extra filter lists available and the option to read and create your own custom filters from hosts files.
Download Ublock Origin: Chrome , Firefox
4. Poper Blocker (Chrome)
Rather than be an all-in one blocking solution, Poper Blocker (aka Pop Up Blocker For Chrome), is designed to complement other adblockers.
In this case, Poper Blocker focuses on blocking pop-ups, pop-unders, overlays, timed and scroll pop-ups, and other varieties that might slip past other ad-blocking extensions. Small notifications tell you when pop-ups are blocked. You also can view your blocking stats, but otherwise, you can generally just keep Poper Blocker running in the background with minimal impact alongside other adblocker extensions.
Download Poper Blocker: Chrome
5. Stands Fair AdBlocker (Chrome)
For a fast and light ad-blocking plugin, Chrome users can turn to Stands Fair AdBlocker. The extension does precisely what it promises, blocking ads and pop-ups from cluttering up your browser view while also preventing any tracking from going on.
Stand's Fair AdBlocker gives you control over the type of ads you can block, specifying everything from autoplay video ads, YouTube ads, expanding ads and more. It can even block Facebook ads if you want.
The "Fair" part of AdBlocker comes into play by giving you the ability to allow certain types of ads or even whitelist ad-supported websites you don't want to shortchange of badly needed revenue. This is one ad blocker that doesn't take a scorched earth approach to its stated purpose.
Download Stands Fair AdBlocker: Chrome
6. Ghostery (Chrome, Firefox, Opera, Safari, Edge)
Like the other extensions on our list of the best ad blockers, Ghostery can remove ads from webpages, so you can focus on content and browse more efficiently. But the real value in Ghostery lies in its privacy protection features. You can use Ghostery to view trackers, which lets you see who's trying to collect data on you. With Ghostery, you can also stop that tracking from taking place. If you really want to safeguard your privacy, you can turn to Ghostery's Enhanced Anti Tracking to anonymize your data.
Ghostery's a free download that offers basic web protection. More advanced protection starts at $4.99 a month and the $11.99 monthly tier comes with a built-in VPN. There are also versions of Ghostery that work with Android and iOS devices.
Download Ghostery: Chrome , Firefox , Opera , Safari , Edge
7. Adblocker for YouTube (Chrome, Firefox)
YouTube has gotten more aggressive with ads, so the makers of ad-blocking extensions have followed suit. Adblocker for YouTube is a Chrome extension that promises to automatically block YouTube ads, whether we're talking about the pre-roll ad appearing before your video or any text and banner ads that appear on the video itself.
If you prefer Firefox to Chrome, there's also an AdBlocker for YouTube extension that works on that browser. Same name, different developer apparently, but the functionality of stripping out video and display ads remains. This version works on Android devices too.
Download Adblocker for YouTube: Chrome , Firefox
1. AdGuard (Windows, Mac, Android, iOS)
Uses looking for a more robust experience can try out the subscription-based AdGuard, which provides desktop and mobile options to reduce the ads you see when surfing online.
AdGuard on Windows and Mac covers popular browsers, with highly configurable options for ads, content, and tracker blocking, as well as a parental controls module for restricting adult content. AdGuard for Android is a no-root ad-blocker that blocks advertising on apps and games, though you’ll have to install it from AdGuard’s site instead of through Google Play. AdGuard for iOS works with Safari to effectively filter ads on the default browser.
Download AdGuard: Windows , Mac , Android , iOS
2. AdLock ($33 per year)
AdLock avoids the browser-based route, instead opting to run as a separate program to be able to block not only browser-based ads, but also advertising in other programs like Skype or games.
The app runs in the background, using filters to block ads, popups, and autoplaying videos, speeding up loading times and applying Safe Browsing features to automatically block sites that are known to be unsafe.
For obvious reasons, the mobile version is unavailable on the Google Play Store, so you'll need to sideload the app if you want to get AdLock into your Android device. iOS users can download AdLock directly from Apple's App Store.
Download AdLock: Windows , Chrome , Android , Mac , iOS
3. Wipr (macOS, iOS; $1.99)
If you’re a Safari fan, Wipr may be the best ad blocker for both your Mac and iPhone. The app is available for both iOS and macOS — costing $1.99 from either Apple App Store — and it promises to work with Safari as well as apps that use Safari for displaying web pages.
You’ll find a full array of features with Wipr, which not only blocks apps and trackers, but cryptocurrency miners, EU cookie and GDPR notices and anything else that gets in your way of surfing the web. Its blocklist gets updated twice a week, and there’s little configuration; the idea is that you load Wipr and forget that it’s there while it does its job in the background.
With Wipr, pages should load faster in Safari, which will be particularly welcome if you’re surfing from an iPhone, where ads and trackers can bog down your browser’s speed.
Download Wipr: macOS , iOS
1. 1Blocker (iOS)
1Blocker was one of the first really good ad blockers on iOS when Apple opened up that functionality on iPhones and iPads; the apps has since been optimized for Safari.
The app is designed to make browsing faster and more secure by blocking ads, popups, trackers and other online cruft. Rather than blocking content of a downloaded page, 1Blocker works with Safari's content blocker API to tell the browser what to block in advance, saving time and resources.
1Blocker features more than 115,000 blocker rules, custom regional adblocking settings, and easy-to-use custom rules settings. The app is a free download, with premium features available as in-app purchases.
Download 1Blocker: iOS
2. Firefox Focus (Android, iOS)
Firefox Focus is another addition to Mozilla's family of browsers. This one's a privacy-oriented version of Firefox that bakes in ad-blocking and anti-tracking into a light and functional package. Firefox Focus blocks ads and speeds up browsing, while also working in privacy-friendly features like automatic history and cookie clearing.
Users can selectively block ads, analytics, content and social trackers with easy toggles, turn on a "stealth" mode, and set a default search engine.
Our look at the best Android browsers has more on the various flavors of Firefox.
Download Firefox Focus: Android , iOS
3. AdClear (Android, iOS)
AdClear — or AdClear Plus if you're searching for the iOS version — offers the kind of mobile ad blocking in browsers that similar apps provide. But AdClear takes it one step farther by also blocking ads in apps.
AdClear achieves this through a DNS changer feature that routes traffic through a VPN. AdClear doesn't catch everything in all apps, and in our experience, some apps ran a little slower. But this free download can put a stop to ads interrupting what you're trying to do whether in an app or a browser.
Download AdClear: Android , iOS
1. Decentraleyes (Chrome, Firefox)
Some times, blocking ads can also prevent websites fromn pulling needed resoruces and libraries from third-party sources, breaking web pages in the process. Decentraleyes tries to stop that from happening by acting as a local content delivery network emulator to serve up the files that websites need. By doing so, this extension can stop websites from sending out requests to the likes of Google Hosted Libraries.
Think of Decentraleyes as a complement to ad blockers. In fact, the extension specifically says it can work with uBlock Origin and AdBlock Plus, both of which we recommend up above.
Download Decentraleyes: Chrome , Firefox
2. Opera (Desktop, Android, iOS)
The Opera browser bakes in ad-blocking features into the browser without the need for an extra add-on, while also offering privacy-friendly tools such as an unlimited, built-in VPN service, incognito mode, fraud and malware warnings for suspicious links and pages, and more. In addition, you can further customize Opera's capabilities with a wide array of extensions.
Mobile users need not fret, as the Android version comes with just about everything the desktop version has but built for touch-screen interfaces. On iOS, the mobile version of Opera is listed in Apple's App Store as Opera Touch. (Incidentally, we've got a guide on how you can use Opera to block ads on the iPhone .)
Download Opera: Mac or Windows , Android , iOS
3. Privacy Badger (Chrome, Firefox, Opera)
The Electronic Frontier Foundation's Privacy Badger browser extension was born from the EFF's concerns about the business models of some privacy tools and ad blockers.
Privacy Badger functions similarly to extensions like AdBlock Plus (on which it was based), observing the various tracking tools that advertisers and other third parties might use to track your online activities and selectively blocking them from executing. Built-in learning algorithms adapt to the sites you visit and take any new tracking tools discovered into account.
While not explicitly an ad blocker, Privacy Badger does also block some advertising, depending on how aggressively the ads track you across websites.
Download Privacy Badger: Chrome , Firefox , Opera
4. Tor Browser (Desktop, Android)
The Tor network helps anonymize your internet activity by bouncing the data you send and receive through a distributed anonymous network of routers to foil a common online surveillance technique called traffic analysis, which can reveal the sites you visit or who you're communicating with.
The Tor Browser is an all-in-one package that includes everything you need to surf the net through the Tor network in an easy-to-install portable package. The package includes a modified version of Firefox with privacy aids such as NoScript baked in, and an automatic setup aid that makes it easy to connect to and create new Tor circuits.
On the desktop, you can grab a version of Tor Browser for Windows, macOS or Linux. There's also a version of Tor Browser for Android, which replaces the previous OrBot + OrFox combination recommended for browsing Tor on Android.
Download Tor Browser: Desktop , Android
5. Onion Browser (iOS)
iOS users aren’t left out when it comes to browsing the Tor anonymizer network, with the Onion Browser among the more popular options on Apple’s mobile OS.
Previously a premium app, Onion Browser has since moved to a donation model, opening up access to everyone who wants to download the app, without compromising security or features. The usual caveats apply: Browsing through Tor will slow down the web experience, and some features, like video streams and video files won’t work in order to preserve anonymity.
Download Onion Browser: iOS
How to choose the best ad blocker for you
Many of the best ad blockers are available for free, either as extensions or as standalone apps, though a few, like AdLock, charge a fee. Determine if the free services provide enough ad-blocking to meet your needs or whether a paid app delivers more for your money. You should also figure out if a browser extension will take care of your ad-blocking needs or whether you should consider switching browsers to one with more built-in privacy features.
You can narrow down your choice in ad blockers by deciding specifically what you're looking to accomplish with such an app or extension. Do you just want to stop annoying pop-up ads from appearing or do you want the full range of services, including privacy features and an end to ad-tracking? Grab the ad blocker that ticks off all the boxes on your wishlist.
Some ad blockers, such as AdBlock Plus include filters and the ability to let in non-obtrusive advertising. Others, like AdBlocker Ultimate, take a more aggressive approach. Find out which one best suits your needs and comfort level.
As we noted at the outset, there's also an ethical component to ad blockers. Do you feel comfortable keeping ad revenue out of the hands of sites you enjoy and use for free? As good as the best ad blockers are, that's still a trade-off you need to consider when deciding whether to install one as a browser extension or as a standalone app.

ublock origin for safari? where do I download it?

cant seem to find a download for it. do they make ublock origin for safari? thanks.
No ublock origin.
As these are extensions to a browser, you would look in the Extension Store/Library for each browser to find it. If it isn't there, that's a safe bet to assume that the browser is not supported.

Hay, just wondering what is everyone using for Safari adblocking nowadays? I have been using Ublock Origin through-out Mojave, but now it is not working anymore. I switched to chrome to keep using uBlock Origin, and at the same time picked up AdGuard for Safari for free, but it is impacting Safari so much that some websites will consume more than 4.6 GB of RAM just by itself. The Content Blocker systems are so much less optimized than the previous API models. I am thinking about ditching Safari on macOS because now I think about it again, it has little advantage over Chrome on macOS now, and Google services like YouTube are more optimized in Chrome as well. Handoff works in Chrome as well and bookmarks sync between two browsers too. I will keep on using Safari on iOS and iPadOS for now, as network-level adblocking using "WebBlock" is hyper-effective on iOS-based systems. About privacy, I have G Suite anyway, no ads on most Google services other than things like YouTube and there is no reading of my email for ads or whatever. I see that Chrome now supports 3rd-party Cookie blocking and Cookie whitelisting now. That's pretty much the same as what Safari has introduced since 2016-ish. For search privacy, I am always logged-in to Google and Google will always know what the heck I am searching for anyway. I set the retention period to 180 days, I allow Google services to hold my data because I just can't stand how stupid Google is without my data. YouTube would be irrelevant to me and searches of important days, for example, would direct me to the calendar of a different school with similar short names. Ads would show up in French and German when I use a VPN etc. Any rescue ideas for Safari desktop? If not, time to say bye?

I don't have any memory issues with AdGuard for Safari - it works very well. If anything, content blockers are better optimised memory-wise.
I use Pi-Hole as a DNS Ad blocker server for my home network (on my Pi) and on my Mac and iPhone I use 1Blocker
