About this extension
Quick Translate runs entirely inside your browser using Mozilla's Bergamot
WebAssembly engine. No text you translate ever leaves your device.
How it works:
- Select any text on a webpage
- Right-click → "Translate: ..."
- Translation appears instantly in a floating popup
Supports 19 languages: Bulgarian, Czech, German, Spanish, Estonian, French,
Hungarian, Icelandic, Italian, Dutch, Polish, Portuguese, Romanian, Russian,
Slovak, Slovenian, Albanian, Serbian, Ukrainian.
Translation models (~35 MB per language) are downloaded once from Mozilla's
official CDN on first use, then cached locally. All subsequent translations
are fully offline.
Languages without a direct model pair translate via English automatically
(e.g. German → Russian becomes German → English → Russian).
