I have used Firefox for 7 years and never had it crash once.

I used it for a similar time if not longer and I think it crashed Extremely stable compared to almost any other software. Perhaps the parent means the mobile version. If not I would expect something is wrong with the system, even if visiting the worst pages of the internet.

Not even Firefox Android crashes for me.

Because Microsoft has had a history of caring about privacy? I'd expect something like this from Apple with Safari, but not Microsoft. M$ can't even give its own developer base privacy by allowing all telemetry to be disabled.

Companies don't care about jack shit. Tim Cook doesn't "believe in" privacy, he thinks it helps sell devices (and that lack of privacy could lead to scandal that would hurt sales).

Whether one company is effectively more private than the other has nothing to do with what the company actually believes. It doesn't really matter what they believe. When you compare the two companies, Microsoft arguably has a greater history of embedding tracking in its products than Apple. This isn't to say that Apple doesn't track anything. As far as I'm aware, Apple didn't help the NSA bypass encryption or build backdoors into its OS.

I've never understood the thinking that went behind allowing one site to see the existence of another site's cookie in the first place. I don't think I'm even coming at this with the security hindsight of decades, it's just common sense, isn't it?

Sites A and B both include content from the spying website S, which sets some cookies. Now S can correlate your visits to A and B because it's able to read its own cookies.

This change makes it so that requests A -> S (requests from A to S) and B -> S are treated as A -> S1 and B -> S2 instead.

Now S1 cannot read cookies from S2 and vice versa, even though they are the same site.

When Mozilla comes out with a feature like this it usually whitelists google, microsoft and similar big sites so people can still log in across their network. Anybody know the current list for this feature?

Yes, you can follow the meta-bug here to see the current issues we're working on resolving in a better way: https://bugzilla.mozilla.org/show_bug.cgi?id=1537702

Perhaps unsurprisingly, Microsoft logins are the most glaring exceptions right now (Teams, Logins, Office, Live), and we're working with MS to see if we can find an acceptable fix (or work-around while it's fixed). There are also exceptions for github.dev and history.com right now.

It's worth mentioning that these aren't simply exceptions which blanket enable tracking for those sites, it's just to work around specific breakage.

We're also working around some other specific site logins or features breaking, which would not break if sites called the new requestStorageAccess API appropritately. We're using SmartBlock to shim those cases until the sites can fix it themselves.

How does this relate to the existing tracking protection settings - should I turn off "block all third party cookies"? That setting breaks a few things, but mostly works OK. I'm confused which protection level this new capability corellates to.

Total Cookie Protection is the same as the Tor Browser's first-party isolation sandboxing - third-party cookies can't be used to track you across sites because they're only accessible within the domain they were created on. So you don't have to block 3rd-party cookies anymore, since they'll be sandboxed and unable to be used for tracking.

To be precise, it's third party cookie/storage partitioning, with web compatibility fixes to keep sites working.

This seems to be a middle-ground. You can more confidently allow third-party cookies, which means that certain features that broke with the blocking of all third-party cookies will now be able to work, but you maintain most of the protections that you gained when you used to block them.

So.. Standard? or Off? Ever since this has been announced, I understand how it works, but the browser does not communicate at all which setting level it maps to, or if I even need ETP on at all and it's just always on.

Total Cookie Protection is already on by default in private browsing mode, or strict ETP. Also Firefox Focus on Android. It's being rolled out to everyone in the standard ETP mode now.

It's currently controlled by setting `network.cookie.cookieBehavior` to `5`. (There is also a similar setting for private browsing mode which is already 5 by default).

Why weren't separate cookie jars the default in the first place? I know that browsers other than Firefox have no real incentive to protect your privacy, but I'm wondering why cookies were designed to be shared among different pages in general

Cookies first appeared in Netscape on Oct 13, 1994 [1]. In 1994 the 'web' was a very different place and the current environment of web tracking and invasive advertising companies simply did not exist. And no one saw the privacy invading potential at the time. [1] https://en.wikipedia.org/wiki/Browser_cookie#History

Yes, but someone here quoted an RFC showing that while people may not have understood this in 1994 they did in 1997. And now 25 years later the privacy issue was fixed.

Does someone have a link about the technical details for developers that it might affect (SSO, cookies for subdomains, etc). This is just a marketing post.

There is some detail here: https://developer.mozilla.org/en-US/docs/Web/Privacy/Storage...
