Websites like Facebook and Google make a lot of money creating scripts to see what people do online.

JavaScript has the ability to let any third party script in your website have full power to collect any data they want from your users, including what they type into login & password input boxes, textareas, contentEditable areas, where the mouse moves etc etc etc.

Because of this I have recently removed all things that require third party javascript to be embedded into my site, and now only use frames

Do you trust these companies to have such power when you or one of your users visits your own site?
