At Mozilla, of course we’re fans of Firefox’s built-in, privacy-focused translation feature, but the beauty of browser extensions is the vast array of niche tools and customization features they can provide. Sometimes finding the right extension for your personal needs can profoundly change the way you interact with the web. So if you do a lot of translating on the internet, you might consider using a specialized extension translator. Here are some great options…
I just want a simple, efficient way to translate. I don’t need fancy features.
Simple Translate
It doesn’t get much simpler than this. Highlight the text you want to translate and click the extension’s toolbar icon to activate a streamlined pop-up. Your highlighted text automatically appears in the pop-up’s translation field and a drop-down menu lets you easily select your target language. Simple Translate also features a handy one-click “Translate this page” button.
Simple Translate
Quickly translate selected or typed text on web pages. Supports Google Translate and DeepL API.
Translate Web Pages
Maybe you just need to translate full web pages, like when reading news articles, how-to guides, or job related sites. If so, Translate Web Pages might be the ideal solution for you with its sharp focus on full-page utility.
TWP - Translate Web Pages
Translate your page in real time using Google, Bing or Yandex. It is not necessary to open new tabs.
The extension includes a handy feature if you commonly translate a few languages — you can select up to three languages to easily access with a single-click popup menu. TWP also gives you the option to designate specific websites you always want translated without prompt.
S3.Translator
Supporting 100+ languages, S3.Translator serves up a full feature set of language tools, like the ability to translate full or select portions of a page, text-to-speech translation, YouTube subtitle translations, and more.
S3.Translator
S3.Translator adds the power of Google Translate’s automatic translations to your browser! It supports translation of selected text, entered phrase or whole webpage between any of 100+ languages. New Feature: Language learning!
There’s even a nifty Learning Language mode, which allows you to turn any text into the language you’re studying. Toggle between languages so you can conveniently learn as you naturally browse the web.
To Google Translate
Very popular, very simple translation extension that exclusively uses Google’s translation services, including text-to-speech.
To Google Translate
Right-click a section of text and click the Translate icon next to it to text translate or listen to it in your language.
Simply highlight any text on a web page and right-click to pull up a To Google Translate context menu that allows three actions: 1) translate into your preferred language; 2) listen to audio of the text; 3) Translate the entire page
I do a ton of translating. I need power features to save me time and trouble.
