I was wondering: is there a FF equivalent to the Chrome extension called Hover Zoom. Whenever there's a thumbnail of a picture, or there's an URL redirecting to a picture, you only have to hover your mouse over said thumbnail/URL to get a popup of the picture in original resolution. It's immensely useful, but I can't find a good working FF equivalent.
Same thing with Google Quick Scroll. When you search for something on Google (like say "neogaf I peed my pants"), and you click on a relevant search result, there will be a pop-up on the down-right of the window, and when you click it, the page will scroll automatically to the part where someone said "I peed my pants". It's very useful, so you don't have to scroll the pages searching for something, or use ctrl+f for it.
