Do browsers tell the sites when users are in private mode? Isn't this a major flaw?

Javascript can track your browser's history, installed plugins, screen resolution etc.. Chrome private mode is a joke.
 
I found a GitHub repo that's regularly updated with an interesting little script that checks for chrome, firefox, opera, safari, edge, the whole gamut. Thanks for that, learned quite a bit. :

it's simple fingerprinting of loophole. When you're in a chromium based incognito mode - FileSystem API is disabled - so script can detect incognito mode.

For example - https://jsfiddle.net/w49x9f1a/

visit above link in normal and incognito modes. :D

Nailed it.

I'm sure that's a "feature" that was "forgotten" by our privacy loving friends behind Chrome.

Interesting find. I hadn't heard of any of this till today. Shows there is massive opportunity in browsers.

I just read that Google Canary will be making all this obsolete. Once they roll out this summer, I'm sure everyone will be fixing the hole. They already have it fixed in version 74.0.3718.0, which is downloadable now I believe.
