I consider myself a pretty savvy user, I'm not a web dev but I understand web technologies, javascript and all that and I simply can't use uMatrix decently. Am I supposed to audit every single external resource to whitelist it? For every website I may want to visit? I don't get it. Ublock seems to do an okay job of blocking most ads and tracking stuff so I'll stick to that in the meantime but I would be really interested to see a uMatrix tutorial or something like that.
