How to have auto google translate like Google chrome that translate any other language page to english automatically?

Hi ! Maybe you'd like to give this add-on a try : https://addons.mozilla.org/en-US/firefox/addon/s3google-translator/ It will be compatible with Firefox 57+, according to the developer's comment : https://addons.mozilla.org/en-US/firefox/addon/s3google-translator/reviews/934216/

Thanks!
