uBlock Origin — What We Like / What We Don’t Like

✅ What We Like

  • Free for all users; no donation link, no nags.
  • Granular logger that shows every request and which rule acted.

⚠️ What We Don’t Like

  • Paid apps add cost if you want device‑wide coverage.
  • No dynamic matrix for script control; power tinkerers may miss it.

AdGuard Or uBlock Origin: Which Fits You Better

Performance & Speed

uBlock Origin stays lean by design. The engine relies on static rules with tight memory use and quick evaluation, which keeps page loads snappy even on older laptops. That makes it a safe pick when you want blocking without slowdown. The project’s own description calls out efficiency on CPU and RAM, matching what many users feel in day‑to‑day browsing. uBlock Origin overview.

AdGuard’s browser add‑on is also built to be light. It ships with focused lists and a steady inspector so you can remove page elements in a click. If you like flipping a few toggles rather than tuning a matrix, it offers that workflow out of the box. AdGuard’s docs also explain how filter rules work across their products and how extra lists change coverage. Extension overview · Filters.

Software & Updates

Browser rules changed in 2024–2025. Chrome moved away from the older extension model (MV2) and started shutting it off in stages. That change hit classic content blockers that rely on request‑level interception. Google’s own timeline shows the dates and what flips when. MV2 deprecation timeline.

What does that mean for buyers? On Chrome, many users now install uBlock Origin Lite—the MV3 build with trimmed features—while the original build works best on Firefox, which continues to keep MV2 available. Mozilla has published updates spelling this out. Firefox MV2 status · MV3 in Firefox.

AdGuard’s add‑on follows the same platform rules as any extension, so features that require deeper hooks live in the paid apps. That split keeps the browser add‑on simple and makes the apps the right route when you need system‑wide filtering.

Integrations & APIs

Both tools plug into a large rule ecosystem. You can subscribe to extra lists beyond the defaults (ads, privacy, malware) and add your own lines. For buyers, that means: no lock‑in. If a site slips through, you can bring in a niche list or write a quick cosmetic rule and move on. Docs from both projects cover syntax and scope. uBO dynamic filtering · AdGuard rule syntax.

One bonus in AdGuard’s world is DNS tooling (AdGuard DNS and AdGuard Home). That’s handy if you want network‑level filtering for TVs or game consoles. It won’t replace page‑level cosmetic rules, but it trims a lot of noise before it hits the browser. DNS rule syntax.

Help & Onboarding

If you want training wheels, AdGuard’s Stealth panel gives human‑readable switches: hide referrer, strip tracking params, clean cookies on close, and so on. You can dial it in without learning rule syntax. Some options differ by platform due to browser limits—AdGuard’s own docs mention these gaps—so expect a few labels to vary between the add‑on and the apps. Stealth Mode (extension).

If you like to tune, uBlock Origin’s advanced mode unlocks the matrix. You can drop third‑party scripts by default, then allow only what a site needs. That kind of control can cut trackers to the bone, though it asks for patience in the first week. The wiki gives a clear path to turn it on and learn the basics. Advanced user mode.

Pricing & Seats

AdGuard’s browser add‑on is also free. If you want device‑wide blocking, the paid apps start around $2.49 per month when billed annually for a three‑device Personal license, with a Family license for nine devices and a lifetime option. The official license page lists the plan types and billing notes. AdGuard license page.

ℹ️ Good To Know: On Chrome, the classic uBlock Origin build runs into MV3 limits; many users switch to uBlock Origin Lite or use Firefox for full features. AdGuard’s add‑on stays simple in Chrome, and the paid apps bypass browser limits.

Software & Updates On Apple Devices

On iOS and macOS, uBlock Origin Lite is now available in the App Store. It brings a trimmed ruleset but fits Apple’s model for content blockers. If you live on Safari, AdGuard’s dedicated Safari extension is another easy path with quick toggles and custom lists. uBO Lite on App Store · AdGuard for Safari.

Price, Value & Ownership

Initial Cost $0 $0 (apps add cost if needed)
