About this extension
Companion for Goofish makes goofish.com (Xianyu / 闲鱼) usable if you don't read Chinese, without hiding the original.
  • Dark mode. Goofish's own components are restyled rather than inverted, so photos look right.
  • Glossary. Conditions (99新, 九成新), shipping terms (包邮), seller statistics and slang (懂的都懂, 不刀) are explained offline.
  • Translation. Descriptions and titles can be translated by a provider you choose: free MyMemory, your own AI model (including a local Ollama), or Firefox's on-device model. None is on by default.
  • English search. Type English and get the Chinese terms sellers actually use, e.g. "used sony wh-1000xm5 headphones" → 索尼 WH-1000XM5 耳机. Save searches you repeat.
  • Prices. ≈ € / $ / £ / zł next to every ¥ price, with daily central-bank rates.
  • Listing checks. Flags new accounts, sellers with no sales, low ratings and replica wording (高仿, 1:1, 纯原, 原单…), and shows how the price compares with similar listings on the page. Not a verdict, just things worth a second look.
  • Images. Full-size originals with zoom, a filmstrip and keyboard navigation.
  • Calmer sign-in prompts. The login pop-up that appears while you browse is tucked away, and it stays available when you actually want to chat or buy. Nothing behind a login is unlocked.

Privacy: no account, no analytics, no server of its own. Page text is only sent to a translation provider if you pick one, and Firefox asks for your consent first.

Not affiliated with Goofish, Xianyu or Alibaba.
