Adblock Plus vs uBlock Origin
Updated October 2026 · AppBreakup editorial

Adblock Plus
One of the oldest browser ad blockers, open source, with non-intrusive Acceptable Ads shown by default.

uBlock Origin
Free, open-source, low-overhead content blocker for ads, trackers and malware sites, best on Firefox.
The short answer
uBlock Origin suits people, especially on Firefox, who want the most thorough and lightweight browser blocker with no paid allowlisting. Adblock Plus suits non-technical users who want a simple blocker on every major browser and on mobile. The biggest difference is the business model: Adblock Plus shows Acceptable Ads by default and is funded by fees from large companies, while uBlock Origin is volunteer-built and blocks everything it can.
Adblock Plus or uBlock Origin: our take
Both are open-source extensions licensed under the GPL that block ads, trackers and malicious domains using filter lists such as EasyList and EasyPrivacy. uBlock Origin adds its own lists and also blocks coin miners, pop-ups and anti-adblock scripts, and it is known for low CPU and memory use. Beginners can install it and leave it alone, while advanced users get an element picker, custom filters, per-site switches and a dynamic filtering mode that works like a firewall for scripts and frames. Adblock Plus, made by the German company eyeo, keeps things simple with sensible defaults and fewer advanced controls.
The Acceptable Ads programme is what separates them. Adblock Plus shows ads that meet size and placement criteria by default, and large companies that benefit pay eyeo a licensing fee; you can turn this off in settings. A Premium subscription adds cookie-banner and distraction blocking. uBlock Origin is completely free, seeks no donations and runs no acceptable-ads scheme.
Platform support is the other factor. Adblock Plus is available for Chrome, Firefox, Safari, Edge, Opera, iOS and Android. uBlock Origin has been removed from the Chrome Web Store under Manifest V3 and is being phased out on Edge, so most Chromium users now run the lighter uBO Lite instead; the full version works best on Firefox, including Firefox for Android. Adblock Plus's filtering under Manifest V3 is also less thorough than its old engine. Neither can block ads inside apps, since both live in the browser.
Pick uBlock Origin if you use Firefox and want maximum blocking with no paid exceptions, or if you like fine control. Pick Adblock Plus if you use Safari or a mobile browser, want something that works the same everywhere, and don't mind some acceptable ads, or switch them off.
Which should you pick?
Choose Adblock Plus if…
- Non-technical users who want a simple, widely supported blocker
- You need iOS, which uBlock Origin doesn't list
- Available on every major browser and mobile
- Simple setup with sensible defaults
Choose uBlock Origin if…
- Firefox users who want the most capable, lightweight browser blocker available
- Very efficient on CPU and memory
- Deep controls: custom filters, element picker, dynamic filtering
About each app
What is Adblock Plus?
Adblock Plus is one of the most installed ad blockers, made by the German company eyeo. It blocks ads, third-party tracking and malicious domains using filter lists such as EasyList and EasyPrivacy, and is available for Chrome, Firefox, Safari, Edge and Opera, with mobile options for iOS and Android. Its defining feature is the Acceptable Ads programme: ads that meet criteria for size and placement are shown by default, and large companies that benefit pay eyeo a licensing fee. You can switch that off in settings. The core extension is free and open source under GPLv3+, and a Premium subscription adds cookie-banner and distraction blocking. It suits non-technical users who want a simple install-and-forget option. Many privacy-minded people prefer blockers without paid allowlisting, and filtering under Manifest V3 is less thorough than the old engine.
What is uBlock Origin?
uBlock Origin is the content blocker most power users recommend. It blocks ads, trackers, coin miners, pop-ups, anti-adblock scripts and malicious sites using EasyList, EasyPrivacy and its own filter lists, and it is known for using little CPU and memory. Beginners can install it and forget it; advanced users get element pickers, custom filters, per-site switches and a dynamic filtering mode that works like a firewall for scripts and frames. It is completely free, GPLv3-licensed, developed by volunteers, and does not seek donations or run an acceptable-ads programme. The big change is Manifest V3: Chrome removed the classic version from its web store in August 2026 and Edge is phasing it out, so on Chromium browsers most people now use uBO Lite instead. Full uBlock Origin remains available and works best on Firefox, including Firefox for Android.
