User reviews

Users appreciate the extension's general ad-blocking capabilities and safer browsing experience. However, multiple reviews highlight its ineffectiveness on YouTube and Twitch ads, limited filter customization, and detection by websites leading to access issues. Additionally, concerns about high disk usage were mentioned. Many users recommend using uBlock Origin instead, noting that this extension is not the original and does not perform as expected.

Highly praised by some users for being the best ad blocker available

Cons

Fails to block many ads on YouTube and Twitch, with ads playing despite the extension being enabled
Lacks customization options for enabling or disabling specific filters
Detected by some websites which then prevent users from accessing content or show adblocker warnings
Excessive disk usage which may contribute to SSD wear
