Why uBlock Origin stopped working in Chrome and what changed

Google removed uBlock Origin from the Chrome Web Store in late 2024 because it violates Chrome's new content-filtering rules. The extension still works if you installed it before the removal, but you cannot install it fresh, and Google may disable it entirely in 2025. This happened because Chrome is moving toward Manifest V3, a new technical standard that limits how deeply extensions can filter web content — the core of how ad blockers work.

If you never installed uBlock Origin, or if you want a replacement that will keep working as Chrome changes, you need an ad blocker built for Manifest V3 or one that works outside Chrome's extension system entirely. The good news is that several strong alternatives exist, and some are actually faster or use less memory than uBlock Origin did.

Key Takeaways

  • uBlock Origin no longer installs on Chrome, but Brave Browser and Edge both include built-in ad blocking that works the same way and requires no extension.
  • If you want to stay in Chrome, uBlock Origin Lite is the official Manifest V3 version, though it blocks fewer ads than the original because of Chrome's technical limits.
  • Adblock Plus, AdGuard, and Ghostery all work in Chrome today and use different blocking methods, each with trade-offs in speed and privacy.
  • Switching browsers entirely to Brave or Edge removes the extension problem and gives you ad blocking that cannot be disabled by Chrome policy changes.

uBlock Origin Lite: The official replacement, with limits

uBlock Origin's creator released uBlock Origin Lite specifically to work within Chrome's new rules. It installs from the Chrome Web Store and works on all the same websites as the original. The catch is that it blocks fewer ads because Manifest V3 prevents it from seeing and filtering as much of the page code as the original version could.

In practice, uBlock Origin Lite still blocks most banner ads, video ads, and pop-ups. It misses some of the sneakier ad formats and tracking scripts that the original caught. If you want the closest thing to what you had before and do not mind slightly more ads getting through, this is the fastest path — it is free, from the same creator, and already in Chrome's store.

Brave Browser: Ad blocking built in, no extension needed

Brave is a Chrome-based browser that includes ad blocking as a core feature, not an add-on. You do not install an extension; blocking is on by default and works on every site you visit. Brave also blocks trackers and fingerprinting scripts automatically, which uBlock Origin did not do as thoroughly.

Switching to Brave means you keep your bookmarks and passwords if you import them from Chrome, and the interface looks almost identical. The downside is that you are changing browsers entirely, which takes a few minutes to set up. Brave also shows its own ads in the "new tab" page (you can turn this off), and some people find its privacy features too aggressive for sites that need them to work properly.

Microsoft Edge: Another Chromium browser with built-in blocking

Edge is Microsoft's browser, also built on the same Chromium code as Chrome. It includes a built-in tracker blocker that also catches many ads, and you can add extensions from the Chrome Web Store on top of that. Edge is already installed on Windows, so you may not need to read anything.

Edge's built-in blocking is less aggressive than Brave's — it focuses more on trackers than ads — but you can layer an extension like Adblock Plus on top if you want stronger ad blocking. If you are already using Windows and Microsoft services, Edge integrates more smoothly than switching to a different browser.

Adblock Plus: Works in Chrome, blocks most ads

Adblock Plus is one of the oldest ad blockers and still works in Chrome under Manifest V3. It blocks banner ads, video ads, and pop-ups on most sites. It is free and straightforward to set up.

The main difference from uBlock Origin is that Adblock Plus is slower on very large pages and uses more memory. It also has a controversial "acceptable ads" feature turned on by default, which means some ads still show even though they are blocked — you can turn this off in settings. Adblock Plus is owned by a company that makes money from advertising, which some people see as a conflict of interest, though the extension itself is free to use.

AdGuard: Stronger blocking, works across all your apps

AdGuard is a paid ad blocker (with a free version that blocks fewer ads) that works in Chrome and also as a system-wide tool on Windows and Mac. The system-wide version blocks ads in all your programs, not just the browser, which is useful if you use apps like Spotify, YouTube, or email clients.

The Chrome extension alone is free and blocks most ads, though the paid version ($20 per year) adds more filter lists and blocks ads in apps. AdGuard is faster than Adblock Plus and uses less memory than uBlock Origin did. The downside is that the free version shows a small banner reminding you to upgrade, and the paid version costs money if you want the full feature set.

Ghostery: Privacy-focused blocking with transparency

Ghostery blocks ads and trackers in Chrome and shows you a detailed list of what it blocked on each page. It is free and works well on most sites. Ghostery is owned by a company that sells data about browsing patterns to advertisers, which is a contradiction — they block trackers but profit from tracking data themselves.

If you like seeing what is being blocked and want a lightweight extension, Ghostery works. If privacy is your main concern, the fact that the company behind it profits from your data may bother you. It blocks fewer ads than uBlock Origin or AdGuard, focusing more on trackers than banner ads.

How to choose between them

If you want the closest match to uBlock Origin and do not mind staying in Chrome, use uBlock Origin Lite. It is free, from the same creator, and blocks most of what the original did.

If you are willing to switch browsers, Brave is the strongest option — it blocks ads and trackers without any extension, and you cannot accidentally disable it. Edge is a good choice if you use Windows and want something already installed.

If you want to stay in Chrome and need stronger blocking than Lite offers, AdGuard is the fastest and uses the least memory. Adblock Plus is the most familiar if you have used it before. Ghostery works if you want to see what is being blocked, but it misses more ads than the others.

Frequently Asked Questions

Will uBlock Origin stop working completely in Chrome?

Google has said it may disable Manifest V2 extensions (the original uBlock Origin) in 2025, but no exact date has been set. If you have it installed now, it will likely keep working for several more months. uBlock Origin Lite will continue to work because it follows Chrome's new rules.

Can I use uBlock Origin in other browsers?

Yes. uBlock Origin works in Firefox, Safari, and Edge without any changes. If you want the full original version with no limits, Firefox is the easiest switch — it uses the same extensions as Chrome and looks very similar.

Do these ad blockers slow down my browser?

uBlock Origin Lite and AdGuard are the fastest. Adblock Plus and Ghostery are slightly slower on large pages. Brave and Edge with built-in blocking are faster than any extension because the blocking happens before the page even loads.

Which one blocks the most ads?

Brave's built-in blocking and the original uBlock Origin (in Firefox) block the most. In Chrome specifically, AdGuard and uBlock Origin Lite block the most ads, with AdGuard slightly ahead on video ads.

Is it safe to use these ad blockers?

All the ones listed here are safe. They are open-source or from established companies, and none of them steal your data or inject ads. The main difference is that Adblock Plus and Ghostery's parent companies profit from advertising or tracking data, while AdGuard and uBlock Origin do not.
