Chrome's private browsing is broken

This defeats the purpose of Incognito. If any website is able to tell you're browsing in private mode, then the browser is leaking data that shows it's not private

@cypnk I wonder *how* they notice it. Also, does it work in Firefox?

@rysiek It seems to work in FF. I have no-script installed and settings to forget all cookies on exit. Which I guess is a roundabout way to get "Incognito"

@cypnk there's a private browsing mode in FF too. What I wonder is if this site detects FF private mode too.

@rysiek Yup. It does. It only happens when I enable JavaScript so Firefox is leaking incognito mode info as well

@cypnk right, so they're using JavaScript to detect this? Interesting.

@rysiek @cypnk afaik it's possible to detect visited links, so you can check if a specific url has been visited.
If history is turned off entirely, you can add a redirect or push a history item through JS, then add an <a> element somewhere with the same URL and check its state.
