What is hooverZoom?

'hooverZoom' is a lightweight Firefox add-on that aims to enhance the browsing experience on media-rich websites. It pops up a full-size image or video file when a user hovers the mouse over a link, eliminating the need to click. The add-on can dynamically load image content, navigate photo albums with mouse or arrow keys, load MP4 videos to replace animated GIFs, and optionally adds links with shown popups to the browser history. After installing the add-on, users need to refresh the pages for effects to take place.
