So I guess for Firefox users it's time to enable the resist fingerprinting option ?

[phr34ky@lemmy.world]

I've used this. The only annoyance is that all the on-screen timestamps remain in UTC because JS has no idea what timesone you're in.

I get that TZ provides a piece of the fingerprint puzzle, but damn it feels excessive.

[treadful@lemmy.zip]

And automatic darkmode isn't respected, and a lot of other little annoyances. That's why this is so difficult. These are all incredibly useful features we would have to sacrifice for privacy.

I mean it doesn't hurt but as far as I can tell, it doesn't actually block fingerprinting, it blocks domains known to collect and track your activity. The entire web is run on Google domains so that would be nearly impossible to block.

The crazy part about fingerprinting is that if you block the fingerprint data, they use that block to fingerprint you. That's why the main strategy is to "blend in".

This is why I like Lemmy, never knew canvas blocker was a thing. Thank you.

It's a nice feature for those that actively enable it and know that it's enabled, but not for the average user. Most people never change the default settings. Firefox breaking stuff by default would only decrease their market share even further. And this breaks so much stuff. Weird stuff. The average user wants a browser that "just works" and would simply just switch back to Chrome if their favourite website didn't work as expected after installing Firefox. Chrome can be used by people who don't even know what a browser is.

Does ublock do this?

[krik@lemmy.dbzer0.com]

Or you just switch to LibreWolf where all these settings are already set. It even comes with uBlock preinstalled.

Wait is that why my Firefox giving me errors when I try to log into websites with 2FA?

[sem@lemmy.blahaj.zone]

Why does it do this?

• Math operations in JavaScript may report slightly different values than regular.

PS grateful for this option!

[chulk@lemmy.ml]

I'm still trying to wrap my head around fingerprinting, so excuse my ignorance. Doesn't an installed plugin such as Canvas Blocker make you more uniquely identifiable? My reasoning is that very few people have this plugin relatively speaking.

[grinde@programming.dev]

Some math functions have slightly different results depending on architecture and OS, so they fuzz the results a little. Here's a tor issue discussing the problem: https://gitlab.torproject.org/legacy/trac/-/issues/13018

[happydoors@lemm.ee]

Maybe if they can connect you to your other usage but it’s probably more of their resources and such a small % of the population that it isn’t worth the time to subvert? Idk just guessing here

[refurbishedrefurbisher@lemmy.sdf.org]

Or Mullvad Browser, which is just the Tor Browser without Tor.

There's also IronFox on Android which is more similar to LibreWolf than MV Browser.

[bogasse@lemmy.ml]

But one question I've been asking myself is : then, wouldn't I be fingerprinted as one of the few nerds who activated the resist fingerprinting option?

[oaklandnative@lemmy.world]

I use (and love) Firefox containers, and I keep all Google domains in one container. However, I never know what to do about other websites that use Google sign in.

If I'm signing into XYZ website and it uses my Google account to sign in, should I put that website in the Google container? That's what I've been doing, but I don't know the right answer.

[johnedwa@sopuli.xyz]

Yes. But it's better than being identified as a unique user which is much more likely without it. You can test it yourself on https://amiunique.org/fingerprint

[schadrach@lemmy.sdf.org]

The crazy part about fingerprinting is that if you block the fingerprint data, they use that block to fingerprint you. That’s why the main strategy is to “blend in”.

So, essentially the best way to actually resist fingerprinting would be to spoof the results to look more common - for example when I checked amiunique.org one of the most unique elements was my font list. But for 99% of sites you could spoof a font list that has the most common fonts (which you have) and no others and that would make you "blend in" without harming functionality. Barring a handful of specific sites that rely on having a special font, that might need to be set as exceptions.

[unwarlikeextortion@lemmy.ml]

Dark mode can be recreated using extensions, although the colors most likely won't be as legible as "native support".

I don't see why a similar extrnsion couldn't change the timezones of clocks.

Additionally, I don't see why the server should bother with either (pragmatically) - Dark mode is just a CSS switch and timezones could be flagged to be "localized" by the browser. No need for extra bandwidth or computing power on the server end, and the overhead would be very low (a few more lines of CSS sent).

Of course, I know why they bother - Ad networks do a lot more than "just" show ads, and most websites also like to gobble any data they can.

[sugar_in_your_tea@sh.itjust.works]

Just use Tor browser if you want to blend in. Some sites will probably not work, and I don't suggest accessing banks with it, but it works well for regular browsing.

[ulrich@feddit.org]

No, the best way is to randomly vary fingerprinting data, which is exactly what some browsers do.

Font list is just one of a hundred different identifying data points so just changing that alone won't do much.
