Best for Chrome (2026)
ProBlocker is a free, MV3-native ad blocker with no Acceptable Ads, no account, and no data collection. uBlock Origin Lite is a good alternative if you specifically want the uBlock brand, but it has reduced capabilities compared to full uBlock Origin.
Best for Firefox (2026)
uBlock Origin works with full capabilities on Firefox, which did not adopt Google's MV3 restrictions. ProBlocker is also available on Firefox and a good choice if you want cross-browser consistency.
Best for privacy
ProBlocker and uBlock Origin both collect no data and feature no Acceptable Ads. Neither requires an account or sells a paid tier.
Install ProBlocker
Get ProBlocker from the Chrome Web Store. It installs in seconds, requires no account, and starts blocking ads immediately.
