Adblock Script Tampermonkey Full Guide

Before diving into the code, you need to understand the architecture. Standard extensions use static filter lists (EasyList, EasyPrivacy). These lists are updated periodically. Ad networks have evolved to use randomization and server-side ad injection, which static lists struggle to catch.

Tampermonkey (a userscript manager) works differently. It executes custom JavaScript code after the page loads. A high-quality adblock script for Tampermonkey can:

When we talk about a "full" adblock script, we are referring to a script that handles everything—not just display ads, but pop-unders, trackers, and annoying cookie warnings.

Here's a minimal but powerful script that removes common ad elements and defeats simple overlays: adblock script tampermonkey full

// 2. Remove elements by text content (e.g., "Please disable adblock")
function removeByText() 
    const keywords = ['adblock', 'disable adblock', 'whitelist', 'ad blocker', 'allow ads'];
    const allElements = document.querySelectorAll('body *');
    allElements.forEach(el => 
        if (el.children.length === 0)  // only leaf nodes to avoid removing entire page
            const text = el.innerText 
    );
// 3. Dynamic observer for newly added ads (e.g., infinite scroll)
const observer = new MutationObserver(mutations => 
    mutations.forEach(mutation => 
        if (mutation.addedNodes.length) 
            // Re-run CSS hiding (new elements with ad classes)
            // Also run text-based removal for new warning messages
            removeByText();
);
);
observer.observe(document.body,  childList: true, subtree: true );
// 4. Clean URL tracking parameters (optional)
if (window.location.search.includes('utm_')) {
    const url = new URL(window.location.href);
    ['utm_source', 'utm_medium', 'utm_campaign', 'utm_term', 'utm_content'].forEach(param => 
        url.searchParams.delete(param);
    );
    if (url.toString() !== window.location.href) {
        window.history.replaceState({}, '', url.toString());
    }
}
// Run once after page loads
window.addEventListener('load', removeByText);

})();

Solution: YouTube updates its anti-adblock script daily. You need a dedicated YouTube script from GreasyFork that is updated within 48 hours. Avoid generic scripts for YouTube.

| Feature | Description | |--------|-------------| | Network ad domains | Blocks requests/scripts from 50+ known ad/tracking domains | | CSS selector blocking | Hides/removes 40+ common ad classes/IDs | | Popup blocker | Overrides window.open to block ad popups | | Dynamic content | MutationObserver removes ads loaded after page load (AJAX) | | Iframe blocker | Removes ad iframes from doubleclick, googlead, etc. | | Excludes YouTube/Twitch | (optional — you can remove those @exclude lines to also block there) |

Advertisements have become increasingly aggressive—pop-ups, video ads, tracking scripts, and "disable your ad blocker" walls. While traditional extensions like uBlock Origin work well, they lack fine-grained, real-time control over how ads are removed. Before diving into the code, you need to

Enter Tampermonkey (or Violentmonkey/Greasemonkey). By using dedicated AdBlock user scripts, you gain surgical precision: block specific elements, bypass anti-adblock detectors, and clean up empty containers—all with code you can edit on the fly.

Instead of writing your own, use pre-made scripts:
