Best for Chrome (2026)
ProBlocker is a free, open-source, MV3-native ad blocker with no Acceptable Ads 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 are both open source, collecting no data and featuring no Acceptable Ads. Claims are independently verifiable via the source code.
