Tired of squinting at the screen when you see a picture? Sure, with most thumbnails you could click them to go see the picture at a better resolution. What if though, I could save you that step? Thumbnail Zoom Plus is a Firefox plug-in which shows a full-size image popup when you hover over a thumbnail or image link.
The way it works is simple. You simply 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.
That is only a small sample of the websites it supports out of the box. Want to download this add-on for Firefox? You can get Thumbnail Zoom Plus from the Firefox Add-ons website.
