Extra caution when using Wi-Fi hotspots is never too much. Even people with very little knowledge and hacking skills can snoop your wireless traffic information. Firesheep is a Firefox plug-in developed by security reseachers to point the vunerability of the Wi-Fi hotspots, and as you can imagine it worked quite well. I will post a video to show how it works, so that we can have a better picture of what really happens. On another hand as a way of protecting yourself you can use the Blacksheep, which is another Firefox plug-in developed to let you know when the firesheep is in use on the network you are connected. The blacksheep will not prevent your information for being snooped, but you will at least be aware that someone has the firesheep plug-in on around you.
