getting browser windows size without javascript

It's standard stuff except the "Browser window" part, see the source for how it works.

My first impression was this is just FUD, how are they going to read out the value? But though I don't know how it's done there certainly is a way to do it (e.g. form submission) or does the site already send it back and I'm missing it?

So yeah, this is bad. I can get very common fingerprint with ease but with this one I'm lost. Any ideas?

Sure we can all maximize our browser, not add or remove any toolbars, sidebars and use the same taskbar height. A bit inconvenient and not that easy for people not running say Chrome on Windows.

 

My primary concern re browser fingerprinting is the possibility of linking my true and pseudonymous identities. I address that, and other such concerns, by using a different VM and VPN account for each pseudonymous identity.

Although observers can determine which websites I've visited as hierophant using this VM, that doesn't concern me. If I want to avoid that, I can easily create another VM, and delete it when I'm done.

Am I missing something?

It is a bit of FUD, because the test detects if the HTTP headers that your browser is sending are different from some default values the test considers to be "the best". This has little relevance if you are not using JonDoNym service, because the values are the recommended ones for THEIR service, not for a normal navigation (i.e. 2 JonDoNym users should, in theory, have the same headers, so that a web service can't tell who's who).
