Adblock Test
Want to test your ad blocker? Find out if your browser is truly protected. This free tool checks your setup against 85+ real ad networks and trackers to show you what gets blocked.
How This Ad Block Tester Works
We run three simple steps to check your protection:
1. Detect Your Browser & Ad-blocking Setup
We check which browser engine you use (Chrome, Safari, or Firefox) to tailor the test for your setup.
2. Send Test Ad Requests
We fire real ad requests to ad servers from Google, Facebook, and other networks.
3. Check the Results
If your ad blocker stops the request, it's working as intended. If it gets through, we count it as a leak.
Types of Ads & Trackers We Test
We test across 80+ real ad, tracking, and analytics domains including Google Ads, TikTok, Facebook, Unity, Yahoo, and major OEM tracking systems.
Why Some Ad Block Tests Are Inaccurate
Some tools only check a small set of static domains. Others ignore whether scripts still load in the background. And some can produce misleading results depending on the browser, blocker, or filtering method being used.
That means a high score does not always equal complete protection, and a low score does not always mean your setup is failing.
Common limitations:
JavaScript Restrictions
Some browsers limit how blocked requests can be detected.
Ad Blocker Behaviour Differences
Some blockers return fake responses instead of blocking requests fully.
Manifest V3 (Chromium Browsers)
Modern Chrome-based browsers limit filtering rules, reducing blocking depth.
What Your Score Means
Higher scores mean better protection. But blocking too much can sometimes break websites. Here's what each range means:
85 - 100(Excellent)— Fortress Mode
Almost everything is blocked. Your ad blocker is working as intended, protecting you from 99% of ads and trackers.
What it means: Very little data leaks out. Note: Some websites may not work correctly at this level.
75 - 85(Good)— Standard Protection
Most ad networks are blocked, but a few invisible trackers got through.
What it means: You won't see most ads, but some tracking data may still leak. This is normal for default settings.
65 - 75(Fair)— Basic Protection
Some gaps in protection. You might see video ads or cookie pop-ups.
What it means: Your filter lists may be outdated, or you have 'acceptable ads' turned on.
Below 65(Needs Work)— Low Protection
Many ad networks got through. Your blocker may be disabled or misconfigured.
What it means: Your browsing is being tracked. We recommend fixing this right away.
How to Improve Your Score
Scoring below 85%? Here are three quick fixes:
1. Update Your Filter Lists
Open your ad blocker settings and update EasyList and EasyPrivacy to the latest versions.
2. Turn On Strict Mode
Enable strict blocking to catch more hidden trackers and sneaky ads.
3. Use Only One Ad Blocker
Running multiple blockers (like uBlock + AdBlock Plus) causes conflicts. Pick one for best results.

What Affects Your Ad-Block Test Results?
Browser Engine
Chromium-based browsers are transitioning to Manifest V3, limiting rule counts. Gecko (Firefox) allows deeper interception.
CPU/RAM Load
Heavy system load can delay script execution, causing "False Passes" or timeouts.
Network Latency
Slow connections might time out a request before your blocker inspects it.
Device Limitations
Mobile browsers often restrict advanced blocking methods.
