While https://panopticlick.eff.org/ is not really new, I learned about that site only recently. And while I knew that browser self-identification would reduce my anonymity on the Internet, I didn't expect this result:

Your browser fingerprint appears to be unique among the 5,198,585 tested so far.

Wow. Why? Let's try one of the others browsers I use. "Appears to be unique", again (where Flash is enabled). What's so unique about my setup? The two reports say about my setup:

Characteristic	One in x browsers have this value
Browser	Firefox 36.0.1	Google Chrome 42.0.2311.68	Chromium 41.0.2272.76
User Agent	2,030.70	472,599.36	16,576.56
HTTP_ACCEPT Headers	12.66	5477.97	5,477.97
Browser Plugin Details	577,620.56	259,929.65	7,351.75
Time Zone	6.51	6.51	6.51
Screen Size and Color Depth	13.72	13.72	13.72
System Fonts	5,198,585.00	5,198,585.00	5.10 (Flash and Java disabled)
Are Cookies Enabled?	1.35	1.35	1.35
Limited supercookie test	1.83	1.83	1.83

User agent and browser plug-ins hurt, fonts alone kill me altogether. Ouch. Update:

• It's the very same when browsing with an incognito window. Re-reading, what that feature is officially intended to do (being incognito to your own history), that stops being a surprise.
• Chromium (with Flash/Java disabled) added

Thoughts on fixing this issue:

I'm not sure about how I want to fix this myself. Faking popular values (in a popular combination to not fire back) could work using a local proxy, a browser patch, a browser plug-in maybe. Obtaining true popular value combinations is another question. Fake values can reduce the quality of the content I am presented, e.g. I would not fake my screen resolution or be sure to not deviate by much, probably.
