To update your ad block lists:

1. On Desktop, Settings > Shields > Content filtering > Update lists button (or go directly to brave://settings/shields/filters)
2. On iOS, Settings > Shields & Privacy > Content Filtering > Update Lists button 
3. On Android, Settings > Brave Shields & privacy > Content filtering > UPDATE button in the top-right

Brave is broadly compatible with uBlock Origin's filter rule syntax. We encourage you to refer to the uBlock Origin Static filter syntax page.

Differences in compatibility are treated as bugs and are documented in the adblock-rust issue tracker.
