I'm pretty convinced this test is quite flawed. My browser of choice is
SeaMonkey, this is a browser built on the Mozilla engine but without all the overhead and bloat which, in my opinion of course, sits in Firefox these days. I personally also like their update policies a lot better.
But, thanks to that Mozilla engine, I can still use some of my favourite plugins such as
NoScript,
AdBlock plus and more common plugins such as Quicktime, Acrobat and even VLC support.
So when I visit this testing page no scripting gets executed what so ever. No Javascript, no Java, no flash. Nothing.
"
Your browser fingerprint appears to be unique among the 2,910,712 tested so far. Currently, we estimate that your browser has a fingerprint that conveys at least 21.47 bits of identifying information.".
So I then visit using Internet Explorer 9, which also has some of the previously mentioned common plugins available (Quicktime, Acrobat, etc.) but this time doesn't necessarily prevent their usage:
"
Your browser fingerprint appears to be unique among the 2,910,715 tested so far. Currently, we estimate that your browser has a fingerprint that conveys at least 21.47 bits of identifying information.".
Rest assured: My MSIE9 is
not unique. The only difference could be the raised security and privacy settings, both are set to "Normal-High". But that's it; its a default installation, with some very commonly used extensions (Acrobat, Flash, etc.) and that's it.
Yet both browsers score exactly the same? That makes no sense what so ever.
