uBlock Origin vs AdBlock

Side-by-Side Comparison

Which Should You Choose?

uBlock Origin is the better pick for most users who want maximum ad-blocking with minimal resource use; AdBlock suits users who want the most widely-installed, no-configuration option.

uBlock Origin holds a 4.7-star rating across 25,364 reviews and is built as an open-source, lightweight filter engine that blocks aggressively by default. AdBlock has a slightly higher 4.8-star rating but across far more reviews (296,855), reflecting its status as one of the most-installed extensions on the Chrome Web Store rather than a difference in blocking power. Both cover the same core use case — removing ads and pop-ups — so the choice mostly comes down to whether you value uBlock's smaller footprint or AdBlock's larger install base and brand recognition.
