Will it make me more fingerprint-able if I install the DuckDuckGo (just for Email Protection, I will not use any of the other features) or Qwacky extension in Mullvad Browser. I want use/access my DuckDuckGo email aliases. I would not be autofilling them, just be generating aliases and copying them…

I agree but that’s not the point, doesn’t answer OP question and spread bold dubious claims. Is that simpler for the average user to follow? Yes Is that accurate? No After all we are here to discuss and understand better, right? I also think people in general obsess too much about fingerprinting…

I don’t think I’m spreading dubious claims by saying one should “assume” it would increase fingerprint. Even though the OP doesn’t intend to auto-fill, does the option to auto-fill increase fingerprint on its own? Maybe it does because it slightly modifies the webpage. Or maybe not because you have …

[image] nateb: Extensions increase fingerprintability. Period. No nuance needed on this one. It doesn’t matter your browser, your VPN, what kind of extension, etc. Some extensions actually can’t be fingerprinted, some can only be fingerprinted in some situations or only based on some user int…

The developer of Qwacky, @Omar , is a member on this forum. You could try asking them directly in the Qwacky thread . You could also install these extensions in a secondary browser, which you only use to manage your aliases, then copy & paste the aliases into your main browser. Since this thread has…

The internet once again proving the addage that the best way to get answers is not to ask questions, but post the wrong answer and wait to be corrected :joy: Thank you all for correcting me. I didn’t know Firefox had added this feature. Does Brave have something similar? They’re usually pretty inno…

I wish browser makers themselves come out and say what’s what why and how when it comes to fingerprinting - its open source so we can even look at their claims and assessment for what and why they consider something a fingerprint and how much of that varies per website. All this discussion while us…

The thing is that AFAIK the makers aren’t the ones doing the fingerprinting. Sure, there’s some stuff they can probably come out and say “hey this makes you stand out” but since other companies are the ones doing it (and they’re not exactly forthcoming about how they do it to protect their trade sec…

[image] nateb: he makers aren’t the ones doing the fingerprinting. Okay I should have been clearer. What I meant is your second sentence. Yes, they could at-least be clear on all the ways websites can fingerprint in the browser. [image] nateb: (and they’re not exactly forthcoming about h…

Are all the means really secrets? Not all of them, but I did a lot of digging for that video I shared earlier and I came up pretty empty other than the well-known stuff and the stuff you can derive from places like Cover Your Tracks. I quoted one company who said they use “hundreds” of data point…
