Info leak in all browsers allows you to check if your friends watch porn

What you mean is it allows me to check it my friends watch porn without clearing their history or using private browsing mode. So basically it allows me to check if my friends have a computer that no one else uses.

"We take advantage of a CSS information leak. Your browser colors visited links differently than non-visited links. All we do is loop through the most popular porn sites and check the link color."

Pretty smart.

I believe you're looking for the word "ingenious" :)

both of you need to be on the internet "more often". It's a CSS history trick at least a few years old.

Ok, you are smarter than me. You win.

I am only smarter because I am online more often. 25/7.

Please, do not insult our intelligence.

Well, there are two sides to this, sure it's lame.

But if you think about it a little longer, it also allows you to make some money of this technique. If you can figure out what other sites people have visited without asking them about it you can target your advertising to that.

Sleazy, sure. But it would work, and I'm sure there will be people doing just that.

could you be more specific? i think most people would be surprised to know that a website can scrape this information out of your browser history.

It's using an old CSS history hack. The part where it asks you to "see where you friends have been" is a complete sham. It just wants to get your facebook credentials to viral-market itself across your address book.

The best it could do is cajole your friends into using it, and then surreptitiously tell you where it thinks they have been .. a gross violation of privacy.

that your browser allows a gross violation of privacy is the point.

spam/viral (checked it on a test facebook account I have)

Doen't pick up the porn sites either (though the code suggests it should); Im on my work PC which has definitely been on some of the sites in the list :)

Firefox Portable FTW!
