This weekend, I started to play around with Jetpack from Mozilla Labs. If you haven’t already heard of Jetpack, it’s a Labs experiment that looks at making the creation of web browser extensions easier. As someone who’s previously tried to make a Firefox extension, I can say wholeheartedly that this was a much, much, much more pleasant experience.
The widget that I created–TinyFinder–looks for rev=canonical links in a webpage, and displays them in the statusbar of the browser window. Rev=canonical links are meta tags that are used when a website wants to suggest a preferred tiny url to use. For example, the Flickr page (http://www.flickr.com/photos/srobbin/3533142101/) can also be accessed by Flickr’s own tiny url (http://flic.kr/p/6odh48). Of course, you could always use one of many url shortening services, but Flickr’s custom URL suggests what you’ll see on the other side of the redirect: a photo/movie. Several services are starting to employ their own custom tiny urls: Dopplr, Threadless, Songza, and many more.

If the web page you are looking at does not provide its own tiny, custom URL, you can always click on the statusbar widget; one will be created for you and automagically copied to your clipboard.
