## What it is
Hover Zoom+ is an open-source browser extension that enlarges images and videos to full size when you hover your mouse over them on supported websites. It is a privacy-respecting rewrite of the original HoverZoom extension, available for Chrome, Firefox, and Edge.

## Use cases
- zoom images on hover while browsing
- view full-size images without clicking through
- preview product photos on shopping sites
- enlarge thumbnails on social media
- view videos inline on hover
- avoid malware-laden image zoom extensions

## When to choose
- you frequently browse image-heavy sites like Facebook, Amazon, or Reddit and want instant full-size previews
- you want a privacy-respecting extension that collects no user data
- you need cross-browser support for Chrome, Firefox, and Edge

## When to avoid
- you use a browser other than Chrome, Firefox, or Edge
- you need zooming on sites not covered by the extension's per-site plugins
- you prefer manual image viewing without hover-triggered popups
