Go to the Firefox Add-on’s Page to add it to your Firefox.
Thumbnail Zoom Plus is a Firefox plug-in which shows a full-size image pop-up when you hover over a thumbnail or image link, like this:
When you hover your mouse over a thumbnail or an image or video link, the add-on displays the full-size image or video still-frame in a floating window.
The image remains visible until you move the mouse outside the thumb, click the mouse, or press Escape. It’s quick and easy to move the mouse from one thumbnail to another to see the corresponding full-size images. For details see our User Manual.
Supported sites include Amazon, Bing, Facebook, Flickr, Google, IMDb, LinkedIn, Netflix, Pinterest, Reddit, Tumblr, Twitter, Yandex.ru, YouTube, Wikipedia, WordPress, Yahoo Images, and many more. For a more complete list see the Compatible Sites page.
Note: To avoid problems we recommend you uninstall or disable the original Thumbnail Zoom add-on before using Thumbnail Zoom Plus.
If you want to try the latest-and-greatest, and don’t mind the risk of a bug or two, consider installing the beta version. Send beta feedback to email@example.com .
Thumbnail Zoom Plus is written by me — David Adler, based on the original “Thumbnail Zoom” add-on, which was written by Andres Hernandez.
