It is now nearly a month since Google launched ‘Extensions‘ for its free web browser, Chrome, so we’ve had a bit of time to play around and test out some of the 1,000 or so extensions available.

Extensions basically allow users to customise Chrome by adding features and functions that they require. A lot like add-ons for Internet Explorer or Firefox.

Here is a list of 10 extensions that we think are worth downloading:

1. Goo.gl url shortener
   This extension allows you to shorten website addresses with Google’s URL shortening service Goo.gl. Once compressed the url is automatically copied to clipboard and you can share it with twitter, facebook, blogger, gmail or your default mail client.
