For those who don't know what BackTrack is, here's a quote from their home page:
There's only half-a-dozen addons in the "vanilla" BT Firefox, and NoScript is one of them. Quite the compliment, directly from the top security guys.BackTrack is a Linux-based penetration testing arsenal that aids security professionals in the ability to perform assessments in a purely native environment dedicated to hacking. Regardless if you’re making BackTrack your primary operating system, booting from a LiveDVD, or using your favorite thumbdrive, BackTrack has been customized down to every package, kernel configuration, script and patch solely for the purpose of the penetration tester.
