backgound.js code (taken from https://developer.mozilla.org/en-US/docs/Mozilla/A...

let proxySettings = {
  proxyType: "manual",
  http: "http://proxy.org:8080",
  socksVersion: 4,
  passthrough: ".example.org",
};

// eslint-disable-next-line no-undef
browser.proxy.settings.set({ value: proxySettings });

the error
Error: proxy.settings requires private browsing permission falls in the console.
although it costs "permissions": ["tabs","proxy","storage"]
why doesn't it work?
