After my first couple of hours with Brave on iOS, I noticed a clear difference on how websites react to the browsers.
- Safari with the Crystal AdBlock-extension:
(Nu.nl homepage)
No banners about AdBlock.
- Brave with built-in AdBlock:
(Same Nu.nl homepage)
Keeps showing a banner about AdBlock.
I use iOS 13.2 beta if you’d like to know.
Keep up the good work
