The fastest way to block ads depends on what you're using
You can block ads three ways: install an ad blocker extension, change your browser settings, or use a browser that blocks ads by default. Most people use an extension because it works on almost every website and takes two minutes to set up. Some browsers like Brave and Opera have ad blocking built in, so you don't need to install anything extra. Your browser's own settings can block some ads, but they won't catch everything.
The method you pick depends on what bothers you most. If ads slow down your pages, an extension helps. If you just want fewer ads on certain sites, browser settings might be enough. If you want the simplest setup with no choices to make, switching to a browser with built-in blocking is easiest.
Key Takeaways
- Ad blocker extensions like uBlock Origin, Adblock Plus, and AdGuard install in seconds and block most ads on most websites.
- Your browser's built-in settings can block some ads and trackers, but extensions block more and work better.
- Brave and Opera browsers have ad blocking built in, so you don't need to install an extension.
- Some websites detect ad blockers and ask you to turn them off or pay for ad-free access before you can read.
- Ad blockers can make pages load faster because ads and their code don't have to download.
Installing an ad blocker extension in Chrome, Edge, or Firefox
The easiest ad blocker to start with is uBlock Origin, which is free and blocks most ads without slowing your browser down. Go to your browser's extension store — that's the Chrome Web Store for Chrome, Add-ons for Firefox, or the Edge Add-ons store for Edge. Search for "uBlock Origin", click the extension, and click the button that says "Add to Chrome" (or "Add to Firefox" or "Add to Edge"). The extension installs in a few seconds and starts working right away.
Other popular ad blockers are Adblock Plus and AdGuard. They work the same way: search for the name in your browser's store, click it, and click the install button. All three are free. The difference between them is small — they all block most ads, but some block slightly more on certain websites. If one doesn't block an ad you see, you can try another.
Once the extension is installed, you'll see a small icon in the top right corner of your browser (or top left on Firefox). You don't have to do anything else. The extension blocks ads automatically. If a website doesn't work right because of the ad blocker, you can click that icon and turn the blocker off just for that site.
Using your browser's built-in ad and tracker blocking
Chrome, Firefox, and Edge all have settings that block some ads and trackers without needing an extension. These settings don't block as many ads as an extension does, but they're a good start if you don't want to install anything.
In Firefox, go to Settings, click Privacy & Security on the left, and scroll down to "Enhanced Tracking Protection". Click "Strict" to block the most trackers. This won't block display ads, but it stops companies from following you around the web.
In Chrome, go to Settings, click Privacy and security on the left, then click "Ad privacy". Turn on "Ad topics" and "Site-suggested ads" to limit the ads you see. This doesn't block ads — it just makes them less targeted to you. Chrome also has a setting called "Block intrusive ads" that removes some very annoying ads, but you have to turn it on in Settings under Privacy and security, then "Ad privacy".
In Edge, go to Settings, click Privacy, search, and services on the left, and scroll to "Tracking prevention". Set it to "Strict" to block the most trackers. Like Chrome, this limits tracking but doesn't block ads outright.
Browsers that block ads without an extension
Brave is a browser built with ad blocking included. You don't install an extension — the blocking is already there. When you open Brave, ads are blocked by default. Brave also blocks trackers and fingerprinting, which are ways websites follow you. If you want to support a website you like, Brave has a feature called Brave Rewards that shows you privacy-respecting ads and shares some of the money with the sites you visit.
Opera is another browser with built-in ad blocking. Open Opera, go to Settings, click Ads and pop-ups on the left, and make sure "Block ads" is turned on. Opera also has a free VPN built in if you want to hide your location.
Both Brave and Opera work like Chrome or Firefox — you can install extensions on top of their built-in blocking if you want even more protection. The trade-off is that Brave and Opera are less common than Chrome, so some websites might not work perfectly on them. Test them out first before you switch completely.
What happens when a website detects your ad blocker
Some websites know you're using an ad blocker and ask you to turn it off before you can read. Others ask you to pay for an ad-free version. A few just block you entirely.
When this happens, you have a few choices. You can turn off the ad blocker just for that site by clicking the extension icon and selecting "disable on this site". You can pay for ad-free access if the site offers it. Or you can leave the site and find the information somewhere else.
Most news sites, streaming services, and social media platforms detect ad blockers. Some will let you read a few articles before asking. Others ask immediately. If you use a site a lot and want to support it, paying for ad-free access is fair — the site needs money to stay running, and ads are how they normally get it.
Why ad blockers can make your browser faster
Ads aren't just pictures — they're code that runs on the page. Every ad has to download, and that takes time and data. An ad blocker stops the ads from downloading in the first place, so pages load faster and use less of your internet.
The speed difference is usually noticeable on websites with lots of ads, like news sites or free streaming services. On sites with few ads, you might not see much difference. If your internet is slow or you're on a phone plan with limited data, an ad blocker can save you real time and real money.
Blocking ads on your phone
Phone browsers work differently than desktop browsers. On iPhone, Safari has a built-in setting to block ads. Go to Settings, scroll down to Safari, tap App Clips and Website Settings, and turn on "Block Pop-ups". This blocks pop-up ads but not all ads. You can also install extensions in Safari — search the App Store for "ad blocker" and look for one with good reviews.
On Android, Chrome doesn't have a built-in ad blocker, but you can install extensions. Go to the Chrome menu (three dots), tap Extensions, then search for an ad blocker in the Chrome Web Store. Firefox on Android has better built-in blocking — go to Settings, tap Privacy, and turn on "Enhanced Tracking Protection".
The easiest option on any phone is to use Brave instead of Chrome or Safari. Brave on Android and iPhone has ad blocking built in and works the same way as the desktop version.
Frequently Asked Questions
Will an ad blocker break websites?
Most websites work fine with an ad blocker on. Some sites detect the blocker and ask you to turn it off or pay. A few sites won't load at all. If a site doesn't work, click the ad blocker icon and turn it off just for that site — you don't have to turn it off everywhere.
Can websites see that I'm using an ad blocker?
Yes, some can. They can tell because the ads don't load. That's why some sites ask you to disable it. They can't see which ad blocker you're using or what other sites you visit — they just know ads aren't showing on their page.
Is it illegal to use an ad blocker?
No. Ad blockers are legal in every country. Websites can ask you to turn one off, and they can refuse to let you read if you don't, but they can't punish you for having one installed.
Do ad blockers use a lot of memory?
A good ad blocker like uBlock Origin uses very little memory — usually less than 10 megabytes. Bad ad blockers can slow your browser down, which is why uBlock Origin and Adblock Plus are recommended over lesser-known ones.
What's the difference between an ad blocker and a tracker blocker?
An ad blocker stops ads from showing. A tracker blocker stops websites and advertisers from following you around the web. Most ad blockers also block some trackers. Your browser's privacy settings block trackers but usually not ads.
