In plain English

Translate Web Pages (also known as TWP) is a browser extension for Firefox that translates the content of any web page in real time without opening a new tab. It uses Google, Bing, or Yandex translation services, and you can switch between them by clicking the translation engine icon in the extension menu. The extension works on Firefox desktop and Firefox for Android. On desktop you install it from the Mozilla Add-ons website. On Android you need Firefox version 120 or later, then search for "TWP - Translate For Mobile" in the add-ons section. For Chrome, Edge, and Brave, the README notes that an official release for those browsers is planned for the future, and any previous workarounds involving registry modifications are no longer supported. Once installed, you can choose to translate the current page on demand or set the extension to translate automatically whenever you visit a page in a specific language. You can change the target language from the extension menu at any time. The FAQ explains that the extension needs permission to read and modify page content on all websites because that access is required to perform translations. Regarding privacy, the extension itself does not collect any user data. However, the text of the pages you translate is sent to Google or Yandex servers, which provide the actual translation. The extension cannot translate certain browser-restricted pages like the Firefox add-ons site itself. Contributions to the extension's interface translations are managed through a Crowdin project. The repository also includes build instructions for developers who want to compile the extension from source.

Copy-paste prompts

Prompt 1

I want to build a Firefox extension that translates web pages. Show me how traduzir-paginas-web injects translated content into the DOM and swaps out the original text nodes.

Prompt 2

Walk me through compiling traduzir-paginas-web from source and loading it as a temporary extension in Firefox for local testing.

Prompt 3

I want to add a new translation engine to traduzir-paginas-web. Show me the pattern the existing code uses to call Google and Yandex so I can add a new provider in the same style.

Prompt 4

How does traduzir-paginas-web use the broad host-permission to read and modify page content, and what is the minimal permission set needed for a translation extension?
