Translate a page

Luma translates web pages on your computer, between English and 57 other languages, without sending the page anywhere.

How it works

Translation runs on this computer, with the translation models Mozilla makes for Firefox. The text of the page never leaves your PC.

The first time you translate from or into a language, Luma downloads its model from Mozilla’s servers, once: 20 to 60 MB. After that the language is translated without a connection. Two languages that aren’t English are translated through English, so the first time both models may be downloaded.

Use the translate button

When a page is in another language than Luma’s, a translate button appears in the address bar.

  1. Click the translate button. The Translate this page panel opens.
  2. From shows the language Luma found in the page, Into the language it will translate into. Click either one to change it, and type in Search languages to find a language quickly.
  3. Click Translate.

A message says when the translation is done. The button stays lit while the page is shown translated. The language you pick under Into becomes the one Luma offers from then on; at first it is Luma’s own language (Settings › General › Language).

Go back to the original

Open the panel again and click Show original, or choose Show original in the ⋯ menu or in the menu you get by right-clicking the page. To try another language, change Into in the panel and click Translate again.

From the menus

  • ⋯ menu › Translate into … translates straight into your usual language, without the panel.
  • ⋯ menu › Translate into another language… opens the panel.
  • Right-click the page › Translate into … does the same as the first entry.

When translation isn’t offered

  • Only web pages can be translated: not Luma’s own pages or files opened from your PC.
  • If the page is already in your language, Luma says so and the button doesn’t appear.
  • If Luma can’t tell which language a page is in, open the panel from the ⋯ menu and choose it under From.
