How to Enable Local Translator in Firefox (Project Bergamot)

Firefox is now available with its local translator, which allows you to translate the pages you visit in your language. The main motive behind this local translator is maintaining the privacy of the users. When translating files with this local translator in Firefox, the data will not be sent from client servers.

Privacy has always been the motive behind all the products and services of Mozilla, and with this local translation, their motive is the same. As of now, a built-in translator is available in the latest build of Firefox Nightly, which for sure does have some cons.

To use the translator, you will have to download the translator service pack, and it is a bit slow in comparison to the translators by other browsers. Let’s see how you can enable this local translator in Firefox.

Enable Local Translator In Firefox (Project Bergamot)

Update Firefox Nightly to the latest version.

Next, you need to visit about:config and then you will reach Advanced Preferences. Here, you will see a page with ‘Proceed with Caution‘ written on it, click on ‘accept the risk and continue,’ and you will be headed to the next page.

Before you follow the next steps, you need to keep few things in mind:

  • If you’re using a third-party translator add-on, then you need to search this “xpinstall.signatures.required” preference and set this preference to False.
  • The local translator that Firefox introduced won’t work with the old UI of the Firefox Nightly, and you will have to Enable Firefox New Proton UI to access the feature.

This is the main step:

Search for browser.proton.infobars.enabled and dom.postMessage.sharedArrayBuffer.bypassCOOP_COEP.insecure.enabled this preference, set both to True. In case, any of the preferences is not added, then select Boolean and then click Add icon. Make sure, both set it True.
