How do you cover your tracks in terms of fingerprinting? Is it even possible with rotating proxies and randomized user agent strings?

My browser was rated 'unique' among 238,000 rated so far.  But it was highly rated for blocking traffic tracking.

I don't see how you'd obfuscate your fingerprint. I wonder who is capable of using it other than the big tech companies?

I was going to ask the same thing.  I'm good on blocking but I can be fingerprinted.  I reactivated DDG privacy plugin to see if that would make a difference, retested and got pretty much the same result.

I just happened upon a fingerprint-blocking page on ScriptSafe.  Hoo boy! I don't know enough about this to even try. Here are the options;

Block Browser Plugin Enumeration:   
 (Default: disabled; prevent sites from reading your browser plugin details)

Canvas Fingerprint Protection:   
(Default: Disabled; protect against fingerprinting attempts through <canvas> elements)

Block Audio Fingerprinting:   
 (Default: disabled; prevent fingerprinting via the AudioContext API)

Block WebGL Fingerprinting:   
 (Default: disabled; prevent fingerprinting via the WebGL API)

Block Battery Fingerprinting:   
 (Default: disabled; prevent fingerprinting via the Battery API)

Block Device Enumeration:   
 (Default: disabled; prevent having hardware devices detected via the WebRTC API)

Block Gamepad Enumeration:   
 (Default: disabled; prevent having devices detected via the Gamepad API)

Block WebVR Enumeration:   
 (Default: disabled; prevent having devices detected via the WebVR API)

Block Bluetooth Enumeration:   
 (Default: disabled; prevent having devices detected via the Bluetooth API)

Block Canvas Font Access:   
 (Default: disabled; prevent system fonts from being enumerated through <canvas> elements. May interfere with Google Docs.)

Block Client Rectangles:   
 (Default: disabled; prevent fingerprinting through calculating element rectangles. May interfere with some dropdowns.)

Prevent Clipboard Interference:   
 (Default: disabled; prevent pages from interfering with clipboard actions)

Reduce Keyboard Fingerprinting (for advanced users):

But at an early stage, as one of the few people who block those things and with the bits of identifying info you still can't block, you're probably still unique.

And the bummer about a lot of those things is it takes us back to Browser Wars 1.0 when we would do user-agent testing on websites and write code for specific UAs (we called them "browsers" back then). The transition to "progressive enhancement" by testing for capabilities rather than browser versions was a huge boon to developers. As you block the ability to test for UA capabilities, you lose that.

I'm testing Decentraleyes ext. & a "No Fingerprints" tampermonkey script.  So far, Decentraleyes hasn't interfered with my daily sites.  The userscript has messed up 2 or 3 and had to be whitelisted.

I'm interested how your testing of Decentraleyes comes out.

No problems today.

I just re-ran the browser test in the 1st post

Our tests indicate that you have strong protection against Web tracking, though your software isn’t checking for Do Not Track policies.

IS YOUR BROWSER:
Blocking tracking ads?   Yes
Blocking invisible trackers?   Yes
Protecting you from fingerprinting?   ◕ your browser has a randomized fingerprint

And scanning down the list of numerous "Bits of identifying information" items, my score is 1/4 to 1/10th the average score.

So something seems to be working better than the first test --particularly the fingerprint avoidance.

I added Decentraleyes to Vivaldi.  So far it's playing nice.

After installing I ran the Cover Your Tracks test again.  Still getting fingerprinting.

Added: Canvas Fingerprint Defender and reran the 'Tracks test.

1. The test summary says I'm still showing a unique fingerprint.  Since there are not billions of users using Vivaldi browser this might always be the case.

2. In the more specific test report under Canvas fingerprinting, it showed that my canvas fingerprint was being "randomized".  Cool. a little bit of progress.

That first link led me here

I feel like it might have been posted already, but it’s an interesting overview of tracking methods
