About this Add-on
WINNER of "Best Updated Add-on" in Mozilla's "Amp Your Firefox" contest. Vote now for best overall.
Thumbnail Zoom Plus is a Firefox plug-in which shows a full-size image popup when you hover over a thumbnail or image link.
When you hover your mouse over a thumbnail or a link to an image or YouTube video, 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, Baidu, Bing, Facebook, Flickr, Google, HuffingtonPost, IMDb, LinkedIn, Netflix, New York Times, Pinterest, Reddit, Tumblr, Twitter, Yandex.ru, YouTube, Wikipedia, WordPress, Yahoo Images, and many more. For a more complete list see the Compatible Sites page.
The add-on also supports any site which links directly to image files, imgur pages, or YouTube videos, including reddit.com and many others (this is enabled by the "Others" checkbox in the add-on's preferences).
The add-on's preferences and toolbar menu let you enable or disable sites as desired. Preferences also let you configure the delay until the popup appears, how large the image is zoomed, whether captions should be shown, whether images are added to history, and more.
Note that if the popped-up image wouldn't be at least 20% larger than the thumb, it won't show the popup image. This is a feature, not a bug. If you don't mind the image overlapping the thumb, turn on the "Show pictures using all available space" preference.
You can save the full-size image using "Download Enlarged Image" from the context (right-click) menu.
Hotkeys let you open the popped-up image in a new tab or window, zoom larger or smaller, open preferences, and more.
