What is nytimes.com using now to detect incognito? Enabling filesystem in incognito used to work until a few days ago.

IIRC, the trick is to time filesystem access and deduce you're running from RAM rather than disk, thus in incognito mode.

Interesting, if that's what they're using it should be possible to inject a JavaScript to replace the filesystem access function with a wrapper that induces delay.

Keeping local storage in memory might make sense if Incognito Mode had separate storage for every tab. However, it's just another browser session that gets wiped when the the last tab gets closed – you cannot have multiple parallel ephemeral sessions. I remember having to install Chrome Canary because I needed four separate Chrome sessions simultaneously.

Your workflow is your workflow, but as an FYI Chrome profiles _also_ get their own everything, plus each profile also gets its own incognito session

There is an added benefit to using profiles in that if any other window is open from a separate profile, then all profile context menus acquire an "Open link in ..." menu item which will then list all the other profile names. Unknown why it doesn't do that context menu modification all the time.

If your other profiles are only used for development-time scenarios, you can also choose to "Clear Browsing Data..." on them at will, since you won't be losing anything valuable

Why not use Permanent browsing mode?

I meant Always use Private browsing checkbox.

I don't really care about tracking within a session and private browsing had other downsides (e.g. limited history support). It's the cross session stuff that tends to be creepier in my experience.

Can this fight ever be won? If you've been browsing the internet for more than 5 minutes you already have cookies from some of the major ad networks. Therefore if you do not have cookies from the major ad networks, you're either a brand-new device or an incognito browser. All that is left to do is get in bed with the ad network to ask them if they have good cookies for this session. As it so happens most of the compa…

Maybe they should start randomly sharing adtech cookies through the cloud.

This is similar to what I'd like to see. Sharing cookies is somewhat dangerous since they could have login/user data, but it would totally work to avoid browser fingerprinting. With all the fingerprinting methods (screen resolution, GPU, HW, font-list, etc.) it's a losing proposition to attempt to remove all traces of a unique fingerprint.

Instead I'd like to see a browser that generates such a noisy fingerprint that it is useless: Each time I start an 'anonymous' session, grab a fingerprint from a pool that is sufficiently similar to mine that things render properly (matching resolution for example) but that has also been used by thousands/millions of others.

I whitelist cookies; only sites that I have a known relationship to (e.g., HN, for login) get to set cookies. The overwhelming majority of the web still works just fine. It's trivial to pick out what doesn't, as it either tends to: a. require cookies for some inane task that doesn't need them, and it tells me this b. breaks horribly. Typically, JS trying to access LocalStorage, but not checking whether the call was s…

Or you can just freely allow all cookies from any website that wants to set them (sites will be happy and working), but only for current browser session. You have to remember to restart the browser every now and then, though. Then use whitelist to selectively allow cookies from some "friendly" sites to be stored permanently.

Or use an extension like Cookie Auto-Delete. It clears all cookies set by a given tab when that tab is closed, and lets you whitelist domains which can set cookies which won't be deleted.

But, "lets stuff everything under legitimate interest" is totally valid if it is actually legitimate interest. Opt-in consents under GDPR is probably your worst strategy. The lawful basis you want to be under is contract basis: you gather the information you need for the contract. You hold it until the contract is up and then you delete the information. That's the best for everyone. Legitimate interest is the next be…

You got the legitimate interest wrong. I wont bother explaining, as I am sick of downvoting (would love to discuss recitals), here is presentation from Tim Walters, check the legitinate interest (or the whole, you might be surprised): https://www.youtube.com/watch?v=-stjktAu-7k Bottom line, "the grain" of GDPR is user interest. Not "user expirience", not bussines interest. Users interest. And it is HARD to decide ins…

I don't think we are at odds with what you are saying. I'm 45 minutes through Tim Walters' video and there is absolutely nothing new for me so far. I suspect I'll get to the end and there will still be nothing new for me because I'm starting in the same place he is.

As for your example, I totally agree! Forcing you to log in to a social network to send a package is crazy. I order cheese making supplies on the internet because I have no other way to buy them. Not a single supplier of cheese making supplies even offers to make me log into a social network.

You're making the statement that all sites are blatantly disregarding the GDPR and I think it's because you just don't pay attention to the sites that aren't.

I'll give you an example (which is is cheese making again). I wanted to check the shipping costs for cheesemaking.com. I don't like the fact that they make me fill out all of their order forms before they tell me the shipping cost, but they do. They have a newsletter which they use to do their marketing, but for now I've not signed up for it. When I didn't complete the process, they sent me an email. They asked if something went wrong and said they will hold my order for 48 hours. After that, they will delete all of my information.

And these guys aren't even in the EU (and neither am I, although I work on contract for a company that is). This kind of behaviour is exactly what I expect and I think it is completely in line with the directives. The only thing they were missing is telling me under which lawful basis they were operating in each case.

Is it contract basis? Keep in mind that as far as I can tell, "contract basis" does not actually require a contract to be in place (i.e. you don't have to have consideration), so I think there is an argument for saying that since I contacted them and started to initiate a purchase, following up on why I didn't finish (for a limited time period) is within the directive.

Even if it weren't, it is almost definitely within legitimate interest. To really qualify for that, they would have to offer to let be object, but since they will delete my data after 48 hours I think they are following the spirit of the directive (because you only have to respond within 1 month).

I don't know. I think the reason you keep getting down voted is because you seem to be focussed on something that is different than what everyone else is talking about. It's absolutely true that there are a lot of companies who don't give a flying monkey's about GDPR. But it is untrue that there isn't anyone. The rest is details and as Tim Walters is at pain to explain the GDPR specifically is not prescriptive because they want you to follow the principles not a check list of rules.

I remember around 10 years ago people were calling Stallman paranoid for this. Now he seems more like a prophet: >I generally do not connect to web sites from my own machine, aside from a few sites I have some special relationship with. I usually fetch web pages from other sites by sending mail to a program (see https://git.savannah.gnu.org/git/womb/hacks.git ) that fetches them, much like wget, and then mails them b…

Well, that is a bit paranoid.

I don't think paranoid is the right word, since it implies some kind of (usually unfounded) fear. I don't get the impression that Stallman is actually afraid of anything in particular; he's just doing this to thwart what he thinks are bad practices. So I'd call it extreme, but not paranoid.

I dont think we are talking about the same thing.

I am talking about:

“There might well be a market for personal data, just like there is, tragically, a market for live human organs, but that does not mean that we can or should give that market the blessing of legislation. One cannot monetise and subject a fundamental right to a simple commercial transaction, even if it is the individual concerned by the data who is a party to the transaction." (https://edps.europa.eu/sites/edp/files/publication/17-03-14_...)

Anyway, I was talking about social network requiring your phone number, not market requiring to log in with social network id. And you are talking about bussines where there is a bussines transaction. I am talking about site you surf to.

You can't allow for bytes to sit around on disk in case of crash. Maybe they could encrypt with a key kept in memory? That'd still allow detection of use though.

> "You can't allow for bytes to sit around on disk in case of crash." Just check periodically (at startup?) for orphaned temporary storage data. I'm sure there are other parts of the browser that need to do this sort of thing anyway - expired cache data, for example.

Sure, but those are a different use case.

OK. That was not clear at all to me! Now that I understand that, I understand what you were trying to say a lot better. I still don't think we materially disagree with each other, though. There are lots of sites that are good examples for GDPR. I think it is absolutely true that none of them are trying to harvest and sell your data! I don't see how that could be the case. If you use that as your criteria, I don't think it is possible that you will find an example. Should those sites be banned from the web? I'm not sure, but it wouldn't bother me, that's for sure!
