Sniffing Browser History Without Javascript

Ergasiophobia alerts us to a somewhat alarming technology demonstration, in which a Web site you visit generates a pretty good list of sites you have visited — without requiring JavaScript. NoScript will not protect you here. The only obvious drawbacks to this method are that it puts a load on your browser, and that it requires a list of Web sites to check against. "It actually works pretty simply — it is simpler than the JavaScript implementation. All it does is load a page (in a hidden iframe) which contains lots of links. If a link is visited, a background (which isn't really a background) is loaded as defined in the CSS. The 'background' image will log the information, and then store it (and, in this case, it is displayed to you)."

    Stop overreacting, that is old news and long since fixed. NoScript is no more "malware" than Firefox itself.

    I'm sure you have more crapware and malware installed on your computer that you're blissfully unaware of than you care to admit, yet you single NoScript out for one tiny misstep made and quickly corrected some time back.
