BEWARE ! People who create fake email account to login to social media.
A facebook employee explained me how tracking works. Its not the email address Meta is concerned about. Its the IP, device identifiers and location.
Meta doesnt care about the email at all apart from sending you emails for notification.
Even with a fake email they exactly know who you are. Let's say you visit CNN.com which has facebook tracker. Facebook has the IP and the device identifiers.
Now you login with fake email account on Instagram, facebook knows that's the IP ans the same device hence it "must" be the same person
That's how facebook creates shadow profiles.
I like the EFF, but I don't agree with the report this generates. There are two counters to fingerprinting: have the same fingerprint as everyone else (Mullvad Browser is based on this idea) and to have a unique fingerprint that changes regularly (The CanvasBlocker extension supports this approach).
Since most of the time I'm in Firefox with CanvasBlocker, I want to see unique fingerprints, but also that they keep changing.
There's a decent bit in their site as to how fighting fingerprinting by trying to be more common can make you still stand out, so mullvad may not work out depending on how it implements this concept. Randomizing fingerprinting sounds like it could work (I haven't researched it so I don't have enough info to agree or disagree, but sounds legit at the very least) and expecting their report to understand that is beyond the scope of the tool. I mean, you couldn't actually test that method is effective without recording it over multiple sessions/days/etc. Sure you want a unique fingerprint, but seeing a unique fingerprint once doesn't mean it's working.
For what it's worth protecting against fingerprinting is pretty hard, so don't feel bad if it tells you your browser has a unique fingerprint. For most people (if you're using Firefox) going to the settings and turning on strict tracking protection and "Do Not Track" set to always send is good enough and will probably stop most attempts by blocking domains that will try fingerprinting. And use Ublock Origin, people.
That site says "Your browser has a unique fingerprint" even though I run Firefox, uBlock, Privacy Badger, and have privacy.resistFingerprinting set to true. My main problem may be plugins, once you have more than a few your set can be pretty unique.
Try going down the page and looking for the categories with more than a few bits of identifying information. I'm running LibreWolf with just uBlock Origin and Dark Reader (which I don't think influences results) and I'm able to get nearly-unique, instead of unique (but I do get unique on default settings). TBB gets non-unique, which is a good set of results to compare to.
In my case I noticed that my fonts were really unique so I set browser.display.use_document_fonts = 0. Also I use my WM to set my page resolution to 1920x1080, which seems to have a better fingerprint than the default LibreWolf floating resolution of 1600x900 (and even the letterboxing resolutions, from what I can tell).
I just spent some time testing again and checking for anything else. RFP does force a generic user agent, but unfortunately it keeps the version information and I can't figure out how to change it with RFP on. Would be nice to set it to the ESR version used by TBB (which has lower bits), but I'm not sure if that would lead to a more unique fingerprint (if, say, a feature was detected that is available in later versions but not ESR).
Edit: just tried Mullvad browser, and it's non-unique! Might be the best option.
Edit: interesting to see this was up voted, then downvoted. Would be good to understand why someone disagrees that LibreWolf would be a viable option here.
I don't use Facebook but I'm 100% sure they have my data.
A lot of apps that uses Facebook login, debugger, React Native, etc. allows it to collect as much user data as it can and send it to FB servers because that's the default.
I dont have facebook, and I explicitly tell family not to put my pictures on their facebook pages or mention me at all.
I'm still 100% convinced facebook has my biometric data, my home address, and what I ate for dinner last week.
The amount of data they collect is insane, and intrusive.
Every time it comes up, i'm reminded of a sex worker who was doxed by facebook because she in a parking lot that a former client was in, and it had used proximity data and shit to link her Sex Work Phone/Facebook Account, to her real Phone/Facebook account, which was then given to the client as a suggested contact.
Facebook takes biometric data from pictures that aren't uploaded to the platform. All it takes is for them to have access to the filesystem of the user's mobile OS.
This is why I fullstop do not let people take photos of me where I can help it. I'm fucking tired of being made a datapoint.
Preaching to the choir but good to remind some people. Thats why you avoid or limit use of those services. Use tor or a VPN and use multiple layers of blocking such as DNS and in browser blocking. Also foss only applications where possible.
it is pretty simple actually there's a lot of tools to block and ignore these companies in a lot of ways. you can also choose to not use any other products which is a very simple thing to do as well
There's a lo of information that sites, not only Facebook, use to track you. Email address can be one this. Anyway, I consider that using anonymous email address is a good idea not only to avoid tracking, also for security reasons I case of filtering, for instance.
I think Firefox cookie isolation (not containers) should block that. Also, always use Noscript and block that shit entirely. You will have no Tracking anymore basically
While browser containers won’t work since you’re using the same IP anyway, blocking the trackers themselves would be more effective. DNS blocking, uBlock, and Privacy Badger can help block fb trackers on websites. So fb knows your ip, but at least they can’t track you across other sites.
People say that it’s redundant using Ublock and Privacy Badger together but I’ve tested Ublock without PB and with PB on the cover your tracks site. Without it it states that I’m partially protected and with both on it says I’m covered. I used ungoogled chromium for the test.
I don't know if it is the case here, but uBlock Origin lets some trackers through and redirects them to empty addresses, so they are effectively useless, good as blocked. This is done so the website doesn't detect that you blocked the tracker, in order to avoid breaking website functionality.
There's got to be more metadata involved in fingerprinting. The type of content you're looking at. Maybe even deriving some sort of signature from your mouse movements.
