Fix: UC Browser Adblock Not Working in Windows 10/11/Android

While most modern web browsers require you to install a third-party extension to block ads, the UC Browser comes with a built-in ad blocker. However, several users have reported the UC Browser adblock is not working.

To fix the problem, we have listed a few workarounds to help you resolve this issue once and for all.

How do I fix UC Browser adblock if it’s not working?

1. Use an alternate browser with a built-in adblocker 

UC Browser is blocked in a few countries to comply with the region’s local laws. Fortunately, there are alternative browsers like Opera One browser that offer built-in adblocker. 

Similar to the UC browser, Opera One blocks all kinds of intrusive ads, loads pages faster, and comes with a filter option to unblock ads from any site you want.

Additionally, Opera One browser offers a free VPN for enhanced privacy and security, built-in messenger apps and snapshot features, video pop-out, battery saver, and even an AI.
