What is it?

Hover Zoom+ is a browser extension that enlarges images and videos when the mouse pointer is placed over them. The enlarged view is sized to fit within the browser window, so thumbnails on shopping, social and media sites can be inspected without opening each file. Site-specific plugins define how each supported website is handled.

The project is an open-source successor to the original HoverZoom extension, which was removed from the store after being found to contain malware. This version states that spyware was removed, bugs were fixed, new features were added, and no user data is collected. Because sites change their layouts, the plugins occasionally need updates, and users are asked to report broken zooming through the issue tracker.

The extension is available for Chrome, Firefox and Microsoft Edge, and localization into other languages is managed through Crowdin.
