Hello,
In Linux you can open your terminal and enter $sudo gedit /etc/hosts and there add sites you want to block systemically so it doesn't matter what browser you use, the website won't work without a need to install any third party apps which may be spywares or other cancer you don't want to have.
My question is, can I do something like this on Graphene OS?
I already updated my DNS to block ads but I want to block some websites like Facebook or Instagram to not be able to open it at all.
Can I do that?
