What is the best ad blocker for Chrome?
Adblock Plus vs uBlock Origin vs AdBlock
Three extensions dominate the Chrome ad‑blocking space. Each takes a slightly different approach to speed, privacy, and user control. Here’s how they stack up:
| Feature | AdBlock | Adblock Plus | uBlock Origin |
|---|---|---|---|
| Price | Free (AdBlock official site) | Free | Free (uBlock Origin on GitHub) |
| Open source | No (proprietary) | Partially (Adblock Plus source) | Yes |
| Memory usage (reported) | ~100‑130 MB (ThinkMobiles tests) | ~45‑55 MB (lowest of tested) | Low CPU and memory (ProPrivacy) |
| Blocks YouTube ads | Yes | Yes (Adblock Plus) | Yes (with custom lists) |
| Allow “acceptable ads” by default | No | Yes (Adblock Plus Acceptable Ads) | No |
| User base | Over 60 million | Over 500 million downloads by 2025 (Chrome Web Store) | Millions (no official count) |
Adblock Plus is the most popular but uses the “acceptable ads” whitelist, meaning you still see some ads by default — fine if you don’t mind supporting publishers, annoying if you want a clean page.
Key features to look for in an ad blocker
- Ad blocking effectiveness — does it catch video ads, popups, and autoplay?
- Privacy protection — block trackers embedded in ads.
- Customization — filter lists, whitelist sites, pause for certain pages.
- Performance impact — low CPU and RAM consumption.
Free vs paid options
All three top contenders are free. Some paid options like Total Adblock add extra features (e.g., VPN integration), but the free ones handle the core job well.
The pattern is clear: Adblock Plus offers the broadest compatibility, uBlock Origin the best performance, and AdBlock the most features per user rating. Choose based on your priority.
How do I install an ad blocker on Chrome?
Step 1: Open Chrome Web Store
Visit the Chrome Web Store (Google’s official extension directory) in your browser.
Step 2: Search for an ad blocker
Type “ad blocker” in the search bar. Results will include AdBlock, Adblock Plus, uBlock Origin, and others.
Step 3: Add to Chrome
Click the extension you want, then click “Add to Chrome”. A pop‑up will ask you to confirm permissions. Accept to start the install.
Step 4: Enable and configure
After installation, the extension icon appears in the toolbar. Click it to open settings — you can whitelist certain sites, enable filter lists, or pause blocking.
The whole process takes less than two minutes, yet many users skip it because they think it’s complicated — it’s literally two clicks once you find the right extension.
The implication: installation effort is negligible, so the real decision is which extension to pick, not whether to install.
Is Adblock Plus free to use?
Adblock Plus pricing
Yes, Adblock Plus (the nonprofit‑backed ad‑blocking extension) is completely free. There is no premium tier; the developer (Eyeo GmbH) generates revenue through its Acceptable Ads program.
What is the “acceptable ads” program?
Under this program, Adblock Plus allows certain non‑intrusive ads through by default. Publishers can participate by meeting specific guidelines (Adblock Plus Acceptable Ads criteria). Users can turn this off in settings.
“Adblock Plus is free and lets you customize and control your web experience, including blocking annoying ads and protecting your privacy.” — Adblock Plus official description
What this means: the free price is real — the trade-off is that you may see a few non-intrusive ads unless you toggle the setting off.
How does uBlock Origin compare to Adblock?
Performance comparison
uBlock Origin reportedly uses less CPU and RAM than Adblock. ThinkMobiles tests showed Adblock consuming 100‑130 MB of RAM, while one unnamed blocker (likely uBlock Origin) used only 45‑55 MB (ThinkMobiles 2024 performance benchmarks).
Privacy features
Both block trackers, but uBlock Origin’s open‑source code is auditable by anyone. Adblock offers some tracking protection but is proprietary (AdBlock official site).
Open-source vs proprietary
uBlock Origin is fully open‑source on GitHub (the world’s largest code repository), giving transparency. AdBlock is closed‑source, so you have to trust the developer’s word on data handling.
uBlock Origin’s powerful filter lists can sometimes break websites — you’ll need to manually whitelist sites that rely on scripts. Adblock’s more conservative blocking rarely causes breakage.
The pattern: uBlock Origin wins on transparency and resource use, but AdBlock wins on simplicity and fewer broken pages.
Can I use an ad blocker on Chrome for Android?
Ad blockers for Chrome mobile
Chrome on Android does not support desktop‑style extensions. However, you can use ad‑blocking browsers like Kiwi Browser (which supports Chrome extensions) or install content‑blocking apps system‑wide (Google Chrome support on mobile extensions).
Limitations on Android
Chrome on Android relies on Google’s ad‑filtering built into the browser, which blocks the worst pop‑ups but not video ads. For full ad blocking, consider using Firefox with uBlock Origin, or a dedicated ad‑blocking browser like Brave.

Expert insights
“Ghostery is a free ad and pop‑up blocker that also blocks trackers embedded within ads, enhancing your browsing speed and privacy.” — Ghostery official description
“AdBlock for Chrome removes ads and provides protection from third‑party trackers. It can block pop‑ups, autoplay video ads, and ads on Facebook and YouTube.” — AdBlock official site
The takeaway: both Ghostery and AdBlock emphasize privacy protection and multi-platform blocking as core value propositions.
The bottom line: For Chrome users tired of intrusive ads, the choice comes down to performance versus features. uBlock Origin is the clear winner for speed and transparency, while Adblock Plus offers a gentler approach with its acceptable ads program. If you want a no‑nonsense block that respects your privacy, uBlock Origin is the pick. For casual users who don’t mind seeing a few non‑intrusive ads, Adblock Plus gets the job done with zero cost.
