Ask HN: Auto-consent cookie and other banners browser plugin?

My Firefox is configured to not save history. No cookies or local storage persist across browsing sessions.

The drawback is constantly dealing w/ the same banners regarding cookies, personal data, privacy policy, etc.

I am looking for a plugin to automatically deal (via whatever means) with all these intrusive banners on popular websites.

GitHub would be a great start. There are two intrusive banners: "Join GitHub today..." and "We use optional third-party analytics cookies...".
