A page that translated nothing used to look exactly like a page that needed no translation. This release makes the reason visible and stops one busy engine from silently costing you the whole page.

• When nothing is translated, the popup now shows why (for example "Engine failed: Google: HTTP 429") instead of the button appearing to do nothing.
• Free engines now back each other up: Google, then Microsoft, then MyMemory. A rate-limited engine no longer leaves the page in the original language.
• New free engine: Microsoft Translator, no API key needed. Pick it under More settings > Advanced > Translation engine, or just let it step in when Google is throttled.
• The button no longer flips to "Restore original" when nothing was actually translated, so retrying stays one click away.

New visual identity: the extension now wears the website's editorial vermilion-on-paper palette — popup, settings, welcome page, in-page float button and progress bar, plus a new icon. The translate button's active state is now ink-coloured so it reads clearly against the brand colour. No behavioural changes.

The interface now speaks your browser's language — English or Simplified Chinese — across the popup, settings, the floating menu and every message. Language names follow the same setting.

Also since 1.13:
• File translation no longer hands back an untranslated copy when the engine fails; it says what went wrong and offers no download.
• X (Twitter): tweets are translated paragraph by paragraph, and the sidebar, navigation and tab bar are left alone.

v1.13.0: translation-only display mode, account sign-in entry (cookie-based, no stored credentials), batched file translation (subtitles finish ~40x faster), hidden-node filtering fixes for news sites, short table-cell translation, proper-noun list handling.
