Starting with desktop version 1.75, advanced Brave users will be able to write and inject their own scriptlets into a page, allowing for better control over their browsing experience.
Customize a website’s appearance with custom scriptlets
Brave already offers the cleanest and safest out-of-the-box browsing experience of any Web browser. Users get best-in-class 3rd-party ad and tracker blocking, privacy protections, cookie notice blocking, and many other enhancements (read more on our privacy updates blog series). Most importantly, these features are enabled by default, so users get the best possible experience the moment they install Brave. There’s no need to manually install Web extensions (and take on the risk of malware) or worry about Google’s Manifest V3 changes. With Brave, things just work.
