- For Internet Explorer there is the Internet Explorer Developer Toolbar which is free (as in beer) and as of writing this required no WGA silliness.
- And the bonus tips: if you are using Firefox, it may be worth to install the User Agent Switcher plugin and to switch to IE, because exploit sites were known for trying to serve up different exploits for different browsers. If you encounter scripts of type JScript.encoded or VBScript.encoded, you should find this tool useful.
Warning! These methods actually execute the script on your machine! They should be used with extreme care, and preferably only in controlled virtual machines or computers not connected to network.
