Simple popup translator API — Gustavo

This is a lightweight browser extension that provides quick access to translation functionality directly from your browser. Type or paste any text you want to translate, select your source and target languages, and get instant translations without leaving the current page.


Simply displays the Google Translate form in the extension's pop-up.


I wasn't finding any simple extension that just allowed me to use the translator on any page. All the ones I tested translated some selected text or didn't open the popup. So here we are with this extension.
