Summary

  • Spanish- and Portuguese-speaking users can now use the complete extension interface in their browser language instead of falling back to English.
  • Add full Spanish and neutral Brazilian Portuguese translations across onboarding, settings, popup, X-Ray, Firefox containers, and contextual help.
  • Select es-* and pt-* automatically, keep English as the fallback, and localize release announcements in both languages.
  • Keep technical API names intact while using context-aware terminology for privacy and spoofing concepts.

Validation

  • pnpm task lint
  • pnpm task check
  • pnpm task test:unit
  • Both targets still build (pnpm task build:chrome, pnpm task build:firefox)
  • Worker bundle regeneration is not required (packages/refract-core is unchanged)
  • Focused i18n and release-notification tests pass
  • Manually verified onboarding, settings, and popup with Chromium locale pt-BR; no horizontal overflow

Changelog

  • I updated CHANGELOG.md in ## [Unreleased] for user-facing changes.
  • This change does not need a changelog entry (internal/test/CI/refactor only).

Summary by CodeRabbit

  • New Features

    • Added complete Spanish and Portuguese translations across settings, popup, onboarding, profiles, rules, trusted sites, sidebar, demo, and About pages.
    • The interface now automatically follows the browser’s language, with English as a fallback.
    • Added Spanish and Portuguese translations for selected release notifications.
    • The language setting displays the active language and available language options.
  • Documentation

    • Updated project structure documentation to reflect the supported interface languages.

Note

Add Spanish and Portuguese UI translations with automatic browser-language detection

  • Adds complete es and pt translation catalogs covering all UI sections (popup, options, rules, trusted-sites, sidebar, welcome, advanced, about, demo, locations, firefox-containers, osm, common, shared-worker) with dynamic count and brand-name interpolations
  • Introduces resolveUiLocale in index.ts to pick the catalog from the browser's navigator.language, defaulting to English for unsupported or absent languages; sets the document root lang attribute accordingly
  • Updates LanguageCard in options-preference-sections.tsx to display the resolved UI_LOCALE and list English, Spanish, and Portuguese selector entries (still disabled)
  • Adds localized title and message paragraphs for release notifications in extension-notifications.json and updates readApprovedBuildStrings in retired-name.ts to validate every locale in the catalog
  • Expands i18n coverage and locale-resolution tests to iterate all *-sections directories and verify es-*/pt-* regional tags resolve correctly
  • Behavioral Change: UI_LOCALE is now dynamic instead of always English; documents receive es or pt as their root language attribute when the browser language matches, and the advanced language status badge changed from SOON to AUTO

Macroscope summarized 78e1781.

📝 Walkthrough

Walkthrough

The PR adds complete Spanish and Portuguese interface translations. Browser language selection now chooses Spanish or Portuguese, with English fallback. Release notifications and the language preference display use the localized data.

Changes

Multilingual interface

Layer / File(s) Summary
Locale selection and UI wiring
src/ui/i18n/index.ts, src/ui/i18n/index.test.ts, src/ui/i18n/i18n-usage.test.ts, src/ui/options/components/tabs/*
The UI resolves browser languages to en, es, or pt. It selects the matching translation bundle, updates the document language, and displays the selected locale in the language preference control.
Spanish translation catalog
src/ui/i18n/es.ts, src/ui/i18n/es-sections/*
Spanish catalogs cover the shared UI, settings, popup, rules, profiles, sidebar, setup flow, About page, demo, and Firefox Containers.
Portuguese translation catalog
src/ui/i18n/pt.ts, src/ui/i18n/pt-sections/*
Portuguese catalogs cover the same UI areas, including pluralization helpers, dynamic labels, brand interpolation, and external-map consent text.
Localized release notifications and documentation
src/shared/extension-notifications.json, src/shared/release-notification.test.ts, CHANGELOG.md, docs/project-structure.md
Five release notifications add Spanish and Portuguese content. Tests cover Spanish and Portuguese notification lookup. Documentation records the supported languages.

Inline comments:
In `@src/shared/extension-notifications.json`:
- Line 24: Update the Portuguese notification copy near “Obrigado” to use
gender-neutral Brazilian Portuguese wording, such as “Agradecemos por usá-la”,
while preserving the remainder of the message.

In `@src/ui/i18n/es-sections/popup.ts`:
- Around line 81-100: Update notificationsBadgeLabel and protectionCounts to use
complete Spanish singular and plural phrases based on each count: pluralize
notifications, protected, degraded, native-by-policy, not-applicable, and
unknown labels when the count is greater than one, while preserving singular
wording for a count of one.

In `@src/ui/i18n/pt-sections/options.ts`:
- Line 44: Update the timeLocale option description to use the JavaScript API
name Date instead of the translated word Data, while preserving the surrounding
Portuguese text and ${BRAND_DISPLAY_NAME} interpolation.

In `@src/ui/i18n/pt-sections/popup.ts`:
- Around line 82-101: The Portuguese labels in notificationsBadgeLabel and
protectionCounts need complete pluralization for counts greater than one. Update
the notification adjective and each protection summary label to use plural
noun/adjective forms when its count exceeds one, while preserving the singular
forms for count one and the existing bucket aggregation.

In `@src/ui/i18n/pt-sections/rules.ts`:
- Around line 48-49: Update the overridesBadge formatter to return a complete
Portuguese noun phrase: use “configuração personalizada” for count 1 and
“configurações personalizadas” otherwise, with the count preceding the phrase.

In `@src/ui/i18n/pt-sections/sidebar.ts`:
- Line 24: Update the acceptLanguage label in the sidebar translation to the
exact protocol name “Accept-Language” instead of a translated phrase.

In `@src/ui/i18n/pt-sections/welcome.ts`:
- Around line 41-42: Update the privacy-policy sentence fragments in the welcome
translation so their concatenation reads naturally as “Leia a política de
privacidade”; adjust descriptionBeforePolicy and/or policyLink without
introducing duplicate articles or missing separators.
