If you haven’t already got it installed I highly recommend the TinyURL Creator Firefox Extension. I’ve been using it more and more recently, simply browse to a page and right click, select ‘Create TinyURL for this Page’ and it generates the url and places it on the clipboard ready for you to paste.
For those who don’t know what a TinyURL is TinyUrl is a service that takes a long URL as input, and gives you a short URL to use in it’s place. For example the TinyURL for https://www.virtualchaos.co.uk/blog/ is http://tinyurl.com/39sbbh. This comes in useful if you want to put a link into Twitter or in an SMS message where you have a limited number of characters to use. I’ve been using the service a lot, but it’s so much easier with the firefox extension.
