Google™ Translator Firefox

Google™ Translator

a handy multi-language translator built on top of Google translate.

Features & Capabilities

Google™ Translator is a fast and reliable Chrome extension built atop Google Translate technology to provide seamless multi-language translation. Designed for everyday use, this unofficial but independent addon offers five core features: quick translations via a menu-bar popup, double-click single-word translations on any webpage, translating lengthy texts by selecting text while pressing the "Alt" key, right-click context menu translation, and spell check with automatic corrections.

Rebuilt using modern web-extensions API for improved performance and robustness compared to previous versions, Google™ Translator supports translations to all available languages. While it excludes some lesser-used options due to API limitations, it remains a handy tool for instant and easy translations directly within your browser. Note that this extension is not affiliated with the official Google Translate application or site.

User Reviews

Users praise the add-on for automatic translation, a polished, customizable UI, and the ability to translate text or whole pages quickly. However, reliability is inconsistent: several reviews report it stops working when Google updates its translate endpoints, requiring data updates or patches, and some users note it doesn’t work on newer Firefox versions (e.g., 120). Overall, it’s valued for speed and usability when functioning, but its reliability hinges on Google API changes and browser compatibility.
Pros
  • Automatic translation of text without needing to click
  • Nice UI with color customization and lots of options
  • Front-end wrapper for Google Translate enabling quick page-wide translations
  • Saves time by translating on pages and for unfamiliar words/phrases
Cons
  • Stops working due to changes in Google's translation API, requiring updates or patches
  • Incompatible with newer Firefox versions (e.g., Firefox 120) leading to non-working behavior

Stopped working with "Addon needs to update some data from 'translate.google.com', please try again after few seconds..." and opening Google Translator page.

Fix for Google Translator addon (broken API) The addon stopped working because Google discontinued the google.com/async/translate endpoint it relied on, as well as the TKK token system used as fallback. Solution: Replace the _getEmbedTranslation function in lib/common.js with a call to the stable translate.googleapis.com/translate_a/single?client=gtx API, which requires no token and returns clean JSON. The new endpoint URL pattern: h t t p s://translate.googleapis.com/translate_a/single?client=gtx&sl={from}&tl={to}&dt=t&dt=bd&dt=rm&dj=1&q={word} The response is parsed via data.sentences[].trans to extract the translation, and data.src for the detected source language. The returned object structure is kept identical to the original so the rest of the addon works without any other changes. How to apply: Open the .xpi file with 7-Zip, navigate to lib/common.js, and replace it with the patched version.

Is Google™ Translator Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Google™ Translator requires a lot of sensitive permissions. Exercise caution before installing.
