Introduction: Why Ad Blockers Still Matter in 2025
Advertisements remain the economic foundation of the free internet. They fund your favorite websites, video creators, and news outlets. However, the last decade has also seen advertising grow increasingly intrusive, data-hungry, and manipulative. Between pre-roll video ads, auto-playing banners, invisible trackers, and fingerprinting scripts, it’s no surprise that ad blockers have become essential for millions of users who prioritize speed, privacy, and focus.
In 2025, three major browser extensions dominate the ad-blocking landscape:
- Adblock Plus (ABP) — the original ad-blocking pioneer, known for its “Acceptable Ads” program.
- AdBlock — a user-friendly alternative that now shares the same parent company and philosophy as ABP.
- uBlock Origin (uBO) — the community-driven, open-source project revered for its speed, transparency, and zero monetization.
While these three share similar names and purposes, their values, business models, and performance differ dramatically. This guide explores those differences in detail so you can make an informed choice for your browsing needs.

1. Ownership and Core Philosophy
Understanding who owns your ad blocker—and how they fund it—is critical. Many users are unaware that two of these extensions (Adblock Plus and AdBlock) are owned by the same company and participate in paid ad whitelisting.
| Extension | Developer/Ownership | Philosophy |
|---|---|---|
| Adblock Plus (ABP) | Developed by Eyeo GmbH, a German company founded in 2011. | Advocates a “balanced” approach to advertising by allowing “non-intrusive” ads through its Acceptable Ads program. |
| AdBlock | Originally independent; acquired by Eyeo GmbH in 2021. | Shares ABP’s philosophy and whitelist model, allowing limited ads by default. |
| uBlock Origin (uBO) | Developed by Raymond Hill and a global open-source community. | Built on a strict non-commercial philosophy — blocks all ads and trackers without exceptions or paid whitelisting. |
🔹 Adblock Plus (ABP)
ABP was one of the first mainstream ad blockers. It popularized EasyList filters and user-friendly customization. However, it has faced criticism since introducing its “Acceptable Ads” initiative in 2013 — effectively allowing some ads in exchange for payment from large advertisers.
ABP’s stated goal is to “sustain a healthy, fair internet ecosystem.” In practice, this means balancing user experience with publisher revenue — a philosophy that not all users agree with.
🔹 AdBlock
Initially, AdBlock was the community’s favorite alternative to ABP due to its stricter blocking stance. But after being acquired by Eyeo GmbH (ABP’s parent company) in 2021, it now operates identically, with the same whitelisting system and similar privacy policies.
🔹 uBlock Origin (uBO)
By contrast, uBlock Origin was designed as a pure content blocker rather than just an ad blocker. Developer Raymond Hill has repeatedly emphasized that uBO’s purpose is to protect users, not to monetize attention. It is open-source, donation-supported, and maintained by a community of privacy advocates — making it the only one of the three with zero commercial influence.
💡 In short: ABP and AdBlock belong to a corporate ecosystem; uBlock Origin belongs to the community.
2. The “Acceptable Ads” Controversy
The “Acceptable Ads” program is at the heart of the debate over modern ad blockers.
What Is It?
The program, introduced by Eyeo GmbH, defines “acceptable” or “non-intrusive” ads that meet specific criteria:
- Ads must not be animated or obstructive.
- They must be clearly labeled as advertisements.
- They must not interfere with the main content or autoplay media.
Why It’s Controversial
While small publishers can join the whitelist for free, large companies pay substantial fees to have their ads allowed by default. Google, Amazon, and Microsoft are among those who have reportedly paid Eyeo for inclusion.
Critics argue this transforms Eyeo into a gatekeeper of online advertising — the very system ad blockers were designed to disrupt. Many users install blockers expecting a completely ad-free experience, unaware that these “acceptable ads” slip through by design.
User Control
Both ABP and AdBlock allow you to disable “Acceptable Ads” manually:
- Open extension settings.
- Uncheck “Allow Acceptable Ads.”
- Restart your browser.
However, since this feature is enabled by default, most users never realize their ad blocker is permitting certain paid ads.
By contrast, uBlock Origin has no such compromise. It blocks all ads and trackers unless you explicitly whitelist a site.
3. Performance and Resource Usage
Here’s where the real technical differences emerge.
| Metric | Adblock Plus (ABP) | AdBlock | uBlock Origin (uBO) |
|---|---|---|---|
| Memory Usage | High on multiple tabs | High | Lowest (Highly optimized) |
| CPU Load | Moderate to high | Moderate to high | Minimal (efficient filter handling) |
| Page Load Speed | Slower due to Acceptable Ads scripts | Similar to ABP | Fastest across benchmarks |
| Energy Efficiency | Moderate | Moderate | Excellent, especially on laptops |
| Filter Processing | Older implementation | Same as ABP | Native browser APIs (V3-optimized) |
Why uBlock Origin Wins
uBO was built with efficiency in mind. Instead of reprocessing every filter manually, it uses declarativeNetRequest APIs and compiled filter lists to evaluate content faster. Benchmarks show it uses up to 60–70% less memory and reduces CPU consumption significantly compared to ABP or AdBlock.
This makes a noticeable difference when:
- Running multiple tabs
- Browsing on low-end devices
- Streaming or gaming
ABP and AdBlock, on the other hand, rely on older, script-heavy architectures that add latency, particularly when applying many filter lists.
Real-World Example
On a mid-range Windows 11 laptop (Intel i5, 8GB RAM), tests show:
- uBlock Origin: 1–3% CPU load, 80–100 MB RAM
- Adblock Plus / AdBlock: 6–12% CPU load, 200–400 MB RAM
This difference might seem small on a desktop, but it adds up to noticeable slowdowns and higher battery drain over time.
4. Feature and Customization Comparison
| Feature | Adblock Plus (ABP) | AdBlock | uBlock Origin (uBO) |
|---|---|---|---|
| Element Picker | ✅ Basic | ✅ Basic | ✅ Advanced (CSS selectors) |
| Dynamic Filtering | ❌ | ❌ | ✅ Yes, full control |
| Logger/Inspector | ❌ | ❌ | ✅ Built-in real-time network logger |
| Custom Rules | Limited | Limited | Extensive per-site rule creation |
| Privacy Filter Lists | EasyList, EasyPrivacy | Same | EasyList, uBO Filters, Peter Lowe’s, and more |
| Third-party Tracker Blocking | Partial | Partial | Full spectrum (ads, analytics, scripts) |
| Browser Support | Chrome, Firefox, Edge, Safari | Chrome, Edge, Safari | Chrome, Firefox (best), Edge, Opera |
| Manifest V3 Compliance | Partial | Partial | Fully optimized |
Key Takeaways
- Ease of Use:
ABP and AdBlock win here. They’re straightforward, ideal for casual users who just want fewer ads without touching settings. - Customization and Control:
uBO is built for power users. You can manage dynamic filtering, block specific scripts, or whitelist domains with a click. It even includes an element picker, advanced logger, and real-time network inspector. - Privacy Protection:
uBlock Origin goes beyond ads. It blocks analytics scripts, crypto miners, fingerprinting attempts, and malware domains. ABP and AdBlock only block visible ads and some trackers, leaving more gaps for advertisers.
5. Browser Compatibility and the Manifest V3 Shift
In 2025, Google Chrome’s controversial Manifest V3 extension framework has officially rolled out, limiting how extensions can intercept and modify network requests.
- uBlock Origin adapted early, launching a Manifest V3-compatible version called uBO Lite with efficient declarative rulesets.
- Adblock Plus and AdBlock also updated for Manifest V3, but their heavy reliance on the older blocking method (webRequest API) initially slowed adaptation.
💡 Recommendation: Firefox remains the best browser for full-featured uBO support, as Mozilla continues to support Manifest V2-level blocking power.
6. Privacy and Ethics
- uBlock Origin: 100% open source. No data collection, no telemetry, no tracking.
- AdBlock / Adblock Plus: Collect limited telemetry (anonymized usage stats) and rely on revenue from their paid “Acceptable Ads” whitelist program.
If your top priority is privacy and transparency, uBO is the unequivocal winner.
“The minute your ad blocker accepts money to show ads, it stops being a blocker and becomes another ad network.”
— Raymond Hill, Creator of uBlock Origin
7. Community and Support
| Extension | Community Activity | Update Frequency | Support Channels |
|---|---|---|---|
| Adblock Plus | Active, corporate-led | Regular updates | Support via Eyeo helpdesk |
| AdBlock | Active, same as ABP | Regular updates | Support via Eyeo forums |
| uBlock Origin | Very active, community-driven | Frequent open-source updates | GitHub issues, Reddit, community forums |
uBlock Origin’s developer community is notably transparent. Every change is logged on GitHub, and updates are frequent, with clear version notes.
ABP and AdBlock updates are less open and slower to adopt experimental browser features.
8. Which One Should You Choose?
🥇 Choose uBlock Origin (uBO) if you want:
✅ Maximum privacy and control

→ They are owned by the same company and share identical core policies.
Final Thoughts: Ethics, Efficiency, and Empowerment
Ad blockers aren’t just about removing ads—they’re about taking control of your digital experience.
In 2025, the differences between Adblock Plus, AdBlock, and uBlock Origin reflect deeper values:
- Eyeo GmbH’s “Acceptable Ads” model seeks compromise between users and advertisers.
- uBlock Origin’s open-source ethos prioritizes user freedom, transparency, and ethical integrity.
