Yesterday, I blogged about how FireSheep made it quite easy for the average person to impersonate other users on social networking websites that were using the same insecure wireless network. The simplest thing a user can do is to force secure HTTP (or HTTPS – HyperText Transport Protocol Secure) but this can be a chore manually inserting the “s” into every web address. Furthermore. all it takes is one lapse of concentration and someone can seize the opportunity to impersonate you if they are eavesdropping on the wireless network.
Thankfully, a neat little add-on for Firefox called NoScript can automate that task for you and it’s really simple to setup up. Once installed, here’s what you need to do:
- Click on the “S” symbol in your Firefox status bar at the bottom of your screen then “Options”,
- Click on the “Advanced” tab then the “HTTPS” secondary tab,
- In the first text box, type in a web address which you want to force HTTPS (such as *.twitter.com or *.facebook.com) and place each unique address on its own line,
- Click “OK”.
Now, whenever you visit one of those sites you have entered in you should be automatically be connected securely to the website. One thing to bear in mind is that not all websites allow complete usage of HTTPS or some things may stop working. For instance, Facebook Chat stops working when forcing HTTPS (I have yet to work out how to make it work again – you can see that I have been trying to disable HTTPS for the chat component in the second text box).
NoScript does have other benefits such as automatically blocking JavaScript, Java and Flash objects on a website where many of the nasties can get into your computer. By default, NoScript will block them all so you need to provide permission to allow them to load. If you trust a particular website you can provide permission by clicking on the “S” symbol and then allowing each domain in the list to load its objects. Otherwise, leave them blocked and objects under the listed domains will not load. This is particularly handy for websites with lots of Flash ads and banners as NoScript will block them all for you.
At first, you might need to expend some effort allowing all of the basic sites you visit but after that you should be off and running with minimal fuss.
