Declarative Net Request

Declarative Net Request (DNR) is a technology used by browser extensions to control and customize the content you see online. Instead of actively monitoring and modifying data as it travels, DNR relies on predefined rules set by the user or the extension developer. These rules specify what types of content, like ads or trackers, to block or allow. This approach makes content filtering more efficient and transparent, helping improve your browsing experience by reducing unwanted elements while maintaining security and performance.
