32 Incredible Bookmarklets for Chrome, Firefox, Safari and Internet Explorer
Scroll Down
Look, no hands!
Probably the simplest bookmarklet on this list, Scroll Down does exactly what it says—it scrolls down. Slowly. Sounds silly, but if you're the kind of person who likes to open a long article, sit back and relax while reading, it's exactly what you need. What do you do when you get to the bottom? Well, there's another bookmarklet called Scroll Up, but that would be silly.
GIFExplode
Animation, frame by frame
When you click the GIFExplode bookmarklet, you are asked to select any animated GIF on the currently active website. You're then taken to the GIFExplode web app, which "explodes" the animation into its composite frames, which you can view individually or save.
Wikipedia Footnotes
Check the source
Anyone who frequents Wikipedia is familiar with the little bracketed superscript numbers, which link to the all-important references that make the encyclopedia a trustworthy source. The only problem with these source links is that you can't see what the source is without scrolling all the way to the bottom of the page and interrupting your reading. With the Wikipedia Footnotes bookmarklet, you can simply hover over links, and the source is displayed in a pop-up box.
VozMe
If websites could talk...
Never find yourself without a text-to-speech converter again, thanks to VozMe. Simply highlight some text on a web page, click the VozMe bookmarklet (available in male and female variants) and enjoy the sweet, robotic sounds of the VozMe web app's automatic text-to-speech service.
Slapnotes
Get sticky with it
Slapnotes is a web service that allows you to place virtual Post-It-style notes all over the web. You have to create a (free) account to use the service. Then use the bookmarklet to easily generate notes on any website—they’ll still be there the next time you come back to the page. You can manage, browse, and search all your notes from your account page.
Marklet
Where bookmarklets gather
Hold onto your hats, because things are about to get meta. This bookmarklet keys into the massive bookmarklet database at Marklet.com, to allow you to use virtually any bookmarklet that exists, even if you haven’t saved it to your bookmark bar. Just click the bookmarklet, type something into the search bar that appears, and you'll see a list of all related bookmarklets. Clicking one of the bookmarklets is the same as clicking it in your bookmarks bar, so you'll never be caught without the tool you need.
