Is Wikipedia blocked in your country or location? Then this addon can help! It automatically circumvents the Wikipedia block so that you can still see the Wikipedia content. You don't need any VPN / proxy or other complicated thing. Just install this addon and you will notice that you'll get the Wikipedia content. The only difference is that you'll see 0wikipedia.org in the wikipedia links instead of wikipedia.org. The 0wikipedia.org is a trusted domain that mirrors the exact WIkiPedia content to prevent censorship and stimulate freedom of speech.
