If you’ve used them once you’ll never be able to work without them. Bookmarklets (or Favelets) are tiny Javascript-Snippets, which are stored within a bookmark and add particular functionalities to the browser you’re using. It doesn’t matter whether you browse, bookmark, look up, search, design or program – depending on your interests, bookmarklets can significantly enhance your efficiency and productivity. However, if you take a look around, you’ll find hundreds of sites, which offer favelets of any possible kinds. Indeed, you’ll find thousands of bookmarklets, many of which you aren’t really interested in. What you eventually are interested in, is a hand-picked choice of the most useful snippets you can directly copy and use from one single page.

We’ve chosen some of the most useful bookmarklets, written new ones and listed them below. You’ll find the source, from which a bookmarklet is copied or modified, or a detailed description of the snippets, in the brackets.

To install the bookmarket just drag’n’drop the JavaScript-Code from the link to the toolbar of your browser. To use the bookmarklet select the text on a page or an address of a web-page and click on the bookmarklet. If you don’t select any text or url and click on the snippet, you’ll get a JavaScript window, in which you can input text manually.

If you use many favelets, you might be willing to check out the Blummy Bookmarklet (The Bookmarklet Management Bookmarklet), a free tool for quick access to your favorite web services via your bookmark toolbar.
