MouseTooltipTranslator

What it does

A browser extension that translates whatever the mouse is over, showing the result as a tooltip - no selecting, no clicking, no switching windows, so you keep reading rather than stopping to translate. It also covers PDFs, video subtitles and text inside images, and can read passages aloud. Translation goes through an external service, so turn it off on pages containing material that should not leave your organisation.
