alphadogg writes "Firesheep, the Mozilla Firefox add-on released about a week ago that lets you spot users on open networks visiting unsecured websites, has given creator Eric Butler more than his 15 minutes of fame. More than 542,000 downloads later, Firesheep has thrown Butler into the middle of heated discussions regarding everything from the ethics of releasing the code to the legality of using it to the need for website vendors to clean up their security acts. Butler, who describes himself as a freelance Web application and software developer, reflects on the past week's happenings in a new blog post that reads in part: 'I've received hundreds of messages from people who are extremely happy that the issue of website security is receiving attention. Some, however, have questioned if Firesheep is legal to use. I'd like to be clear about this: It is nobody's business telling you what software you can or cannot run on your own computer. Like any tool, Firesheep can be used for many things. In addition to raising awareness, it has already proven very useful for people who want to test their own security as well as the security of their (consenting) friends. A much more appropriate question is: "Is it legal to access someone else's accounts without their permission."'"
