Unique isn't a bad thing really. The trick is to regularly be unique in a different way. I'd rather each tab have a unique fingerprint than simply trust that there's nothing about my browser/device that could identify me. There is an ever growing list of data points your browser makes available and a lot of time, money, and research that goes into finding fingerprinting techniques.
I agree it's good to have a locked down browser for most things and other browsers for websites that you can't get working with everything blocked. Brave is worth a try before you hand your browsing history over directly to Google with chrome or to MS with edge.
This perspective is new to me, and very interesting. If it's intractable to know which parts of the finger could change, the fingerprinting becomes useless.
With my heavily, via plug-ins, privacy focused firefox I get 99%.
With https://www.amiunique.org/fingerprint I get:
Yes! You are unique among the 2206539 fingerprints in our entire dataset.
PS: with my vanilla Chrome - I use several browsers, for banking and buying plane tickets I always recommend a vanilla one - I get 47% with many things blocked. Is this thing working correclty? I just checked my hosts file and it is vanilla too. I used to have a large hosts file but this is just inconvenient since it breaks sites. I don't understand why so many things may be blocked in my chrome browser.
PPS: I wanted to give it a try in https://browsershots.org/ Is this site defunct? Whata pity.
