Oxford Dictionary Extension for Chrome
This extension only use for individual purpose.
This Extension can't be used if you dont remove the header X-Frame-Options from HTTP response in the chrome. Cuz Oxford prevented you get their page inside an iframe. So i recommend you install additional extension Requestly(https://chrome.google.com/webstore/detail/requestly-redirect-url-mo/mdnleldcmiljblolnjhpnblkcekpdkpa?hl=en) which allow you to modify HTTP Headers by rules per request.
