Grefinition is a simple and user-friendly online translator designed for the Chrome browser. Developed by papasierra88, this free add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

With Grefinition, users can easily translate English words into Greek by simply double-clicking on any English word. This action triggers a popup window that displays the translation of the word into Greek, along with the definition in English. Additionally, if available, users can also listen to a sound recording of the chosen word.

It is important to note that Grefinition is currently unable to function on HTTPS pages due to security restrictions. However, on regular webpages, this extension provides a convenient and efficient way to quickly translate and understand English words in Greek.
