NovaBlock vs Ghostery

Ghostery has been on the privacy scene since 2009. For a decade it was the default tool privacy-curious users installed when they wanted to know who was watching them online. NovaBlock comes from a different angle: instead of teaching you what is happening, it quietly stops it from happening. This comparison walks through what each product does best and which one belongs in your browser today.

If you are still exploring the field, our best ad blocker 2026 guide is a good orientation.

Philosophies

Ghostery's pitch has always been transparency. Click the icon, see a list of every advertising, analytics, social and tracking script on the page. For users who want to learn how the modern web works, this is genuinely educational. The blocking part has improved over the years, but the brand identity is still "the tool that shows you".

NovaBlock's pitch is the opposite. The default state is "nothing is shown to you because nothing got through". The popup tells you what was blocked, but the goal is for you to forget the extension exists. The right amount of UI for an ad blocker is almost none.

Both are valid. They just attract different users.

Visibility and reporting

This is where Ghostery shines and where NovaBlock deliberately does less.

Ghostery's interface lists each tracker by name, with a brief description of what it does, who runs it, and what category it falls into (advertising, analytics, social, customer interaction, essential). Users learn quickly that one news article can include a dozen analytics scripts and half a dozen advertising trackers. That awareness is, in itself, a public service.

NovaBlock's popup shows aggregate counts (ads blocked, trackers blocked, cookies suppressed) and a per-site toggle. There is no per-tracker detail view. We made that choice intentionally because it is easy to drown a non-technical user in noise.

If you are a journalist, researcher, lawyer, or curious power user, Ghostery is the better tool for inspection. For most other users, NovaBlock's "trust the defaults" stance is the calmer experience.

Blocking quality

In our 2026 tests on a clean Chrome 132 profile:

Tracker blocking is essentially tied; this is Ghostery's core competence and it is very good at it. NovaBlock's lead on YouTube and cookie banners reflects the team's focus on those areas. Ghostery does not invest in YouTube specifically the way NovaBlock and AdGuard do.

Privacy of the blocker itself

Ghostery had a complicated decade in the mid-2010s when ownership changed and the product included an opt-in data-sharing feature called GhostRank. That feature is gone. Today's Ghostery is owned by an independent European privacy company, the codebase is open source, and the data practices are clearly documented.

NovaBlock collects no in-product telemetry in either the extension or the Premium account flow. Our privacy page is one page on purpose.

Both are credible in 2026. If you are the kind of user who reads policies, both pass scrutiny.

Business models

• Ghostery offers a free tier plus a paid "Ghostery Plus" subscription that adds historical insights and an ad-free dashboard. The free tier is fully functional.
• NovaBlock offers a free tier covering ads, trackers, banners, pop-ups and YouTube basics, plus a Premium tier for advanced YouTube AI detection and multi-device sync. See pricing.

Neither company runs an "acceptable ads" allowlist or a data-broker side business. That is a meaningful filter; it eliminates several competitors immediately.

Features

Ad blocking

Both have it. NovaBlock is slightly more aggressive by default and includes a stronger annoyance list (cookie banners, newsletter modals, autoplay videos).

Tracker blocking

Ghostery's main event. Both block effectively; Ghostery exposes more detail in the UI.

YouTube

NovaBlock wins clearly, owing to its dedicated YouTube module. See block YouTube ads.

Cookie banners

NovaBlock wins, with banner removal on by default. Detail in remove cookie banners.

Per-site controls

Both expose per-site pause. NovaBlock's UI is one click; Ghostery's is similar but exposes more granular per-tracker toggles for users who want them.

Multi-device sync

NovaBlock Premium syncs across browsers and devices via one account. Ghostery Plus syncs dashboard data but not extension settings as fully.

Pros and cons

NovaBlock pros

• Excellent defaults: install, do nothing, browse faster.
• Best-in-class YouTube and cookie banner handling.
• No in-product telemetry.
• Multi-device Premium sync via one account.

NovaBlock cons

• Less per-tracker visibility for power users.
• Closed source today (engine open-sourcing is on the roadmap).

Ghostery pros

• Outstanding tracker visibility and education.
• Open source.
• Strong reputation in the privacy community.
• Independent European ownership.

Ghostery cons

• YouTube and cookie banner suppression trail NovaBlock by a clear margin.
• UI can overwhelm users who do not want a tutorial.
• "Plus" upsell can feel pushy for users who only want the blocker.

Real-world scenarios

• You want to understand who is tracking you on every site, in detail: Ghostery.
• You want to never think about it and have the page load faster: NovaBlock.
• You are a teacher or trainer showing students how trackers work: Ghostery's UI is a teaching aid in itself.
• You are an EU user tired of cookie banners and YouTube pre-rolls: NovaBlock.
• You write privacy reports and need screenshots of tracker breakdowns: Ghostery, with NovaBlock as your daily driver in another profile.

Can you run them together?

You can, but choose a primary. Put one of them in "inspection mode" (Ghostery is better suited to this) and let the other do the actual blocking. Running both fully active on the same profile occasionally produces minor cosmetic glitches and wastes CPU.

Conclusion

Ghostery is a teaching tool that also blocks. NovaBlock is a blocking tool that also reports. Both are honest products in 2026, run by teams that care about privacy. If you want to see the web in all its tracker-laden glory, install Ghostery. If you want the web to feel calmer immediately, install NovaBlock from the Chrome Web Store or Firefox Add-ons. They are not competing for exactly the same user, and that is fine.
