Scripts in this sense refer to VBScript or Javascript running client-side in the background. There's not a lot you can do that won't severely affect your use of every other website. The problem is to do with bad coding by the site's designers, but turning off javascript will disable it for all site, and many sites use it for navigation - hence you're quite frankly buggered if you turn it off. On the upside, it's only the site with bad coding that won't work properly with the rrors - it can't do you any harm at all.
