> biggest things you can do for your privacy is ad-blocking / cookie cleaning

Very true. But there is no problem with apple, in fact Safari is first browser that is clearing cookies - ITP(2). I use uBlock Origin on Safari and Private browsing - no cookies at all.

Firefox has been able to clear cookies like that for years without any extensions.

Firefox has an option to block all third party cookies in the manner similar to Safari 1-10's default behaviour. And like everything else, it lets you clear all cookies at once, or manually look through the cookies to clear them.

It does not have a feature analogous to safari 11+'s tracking prevention.

I never said that it did... I wrote that firefox has had the ability to block cookies automatically for years, which it has had. My response was not a comparison between the browsers but a statement of one particular feature that was mentioned. I simply said that what had been stated by the gp was also available in Firefox.

When you wrote 'like that', I assumed that you meant 'like that'.

Given that the gp referred to ITP... no, it's not.

The gp has clarified their comment, since that time. Snark is beneath you.

By the time I posted anything, the post clearly referred ITP.

You were ignoring that nine hours later.

The clarification was to add ITP.

Disqus is over that way, if you want to keep arguing without a reason and without reading what others write.

What about the tracking prevention that Private Mode has had since FF 42 or so?

Firefox’s tracking protection is the same feature as Safari’s content blockers. [the defaults differ, though], and prevents specific listed domains from loading anything. Except when it turns out blocking them breaks too much. Like Youtube embeds.

Safari’s tracking prevention applies to things that do wind up getting loaded, and limits access to their own cookies/context. [kind of like loading all those embeds in seperate private sessions, even though they're on the same page]

Usind default settings or manually?

Neither. It's an option in the preferences.

Is that option enabled in default installation of firefox? Sorry, I must have specified that in Safari ITP is enabled by default, and this is important for non-tech people.

The default is 'allow everything'

You can change a setting to block third party cookies. This gets you similar treatment of cookies as was the default in safari 1-10.

Safari 11 still blocks third party cookies by default, but has 'Intelligent Tracking Protection' as an additional filter on top of it. ITP blocks/limits certain uses of first-party cookies.

Firefox has no analogous option. Either cookies are off, or all uses of first party cookies are allowed.

No. It hasn't been enabled by default in my experience. It isn't the exact same as the Safari technology. Firefox lets you block "3rd party cookies" or "all cookies" from the privacy pane of preferences. I've always "set it and forget it". The assumption is that many tracking cookies will come from 3rd party websites.
