Bookmarklets
The most extensive bookmarklet archive list. (afaik)
Bookmarklets are short snippets of JavaScript that can be executed by clicking on a, well, bookmark. That's where they get the name from. I have compiled a list of some free and public bookmarklets here for anyone to use. I don't remember the authors of some of them, but I claim no ownership over any of the following bookmarklets. To install a bookmarklet, simply drag it to your bookmark bar, and then you can click it to activate it.
Please consider supporting us by purchasing bookmarklets over at our store. They are not in this list and are of high quality.
