Developers of the Brave desktop browser are maintaining a set of patches which may interested you:
https://github.com/brave/brave-core/tree/master/patches
Probably, you cherry-pick those related to privacy and security, and add them to the project.
i checked a little bit the list of patches from brave and i have 2 issues about it
So i don't really see a patch that can help this project, but i may missed something can you please point out a patch if you find one useful for this project ?
@pjv Huh. It's always surprising for me to see the impact of this project, considering my scope is pretty limited to GitHub.
@intika Thanks for investigating. For the issues list you found, we could pick applicable ideas to implement. (Please open seperate issues for them.)
@dimqua If you find any Brave patches that are applicable to this project, please let us know.
