Google Translate, the built-in extension of Google Chrome, is a machine translator that provides users with an easy way of translating webpages from within their browser tab. This is the gist of how Google Translate impacts the DOM and an important piece of why Google Translate causes problems (i.e. interferes) with JavaScript apps doing DOM manipulation. See my article How to detect Google Translate and other machine translation for a way to detect when Google Translate is active.
