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. 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. 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.
On OSX Mavericks (and possibly other OSes) if I maximize with Command+Shift+F while a pop-up is displayed, the pop-up is 'stuck' visible. It doesn't pop-down when I move the cursor, press Esc, or even reload the page. The page continues to operate normally except for being partially hidden by the pop-up.
It seems to recover if you hit Command+Shift+F again the exit full-screen and then hover another thumb. Or close the window and then re-open it with Command+Shift+W.
