 ## I need a browser with ad blocking. Which one should I choose?
 Choosing a browser is about as intimate as [choosing a starter Pokémon](https://youtu.be/F_8htiBjTCY), so here's a few caveats:
-* The best browser on paper may not work well in real world usage (e.g., [Brave](https://brave.com/) is wonky with video playback on iOS).
+* The best browser on paper may not work well in real world usage.
 * Browsers are tools! Use a variety of browsers depending on what you need to do.
 * You should use various browsers (or browser profiles) for different areas of life (e.g., work, school, personal).
