Firefox now blocks cross-site tracking by default for all users

[Corrine]

Via Bleeping Computer at Firefox now blocks cross-site tracking by default for all users:

Total Cookie Protection forces all websites to keep their cookies in separate "jars," thus blocking attempts to track you across the web and building browsing profiles.

First introduced with the release of Firefox 86 in February 2021, this privacy feature was only active until now in private browsing or when users would manually enable ETP Strict Mode in the web browser's settings.

"Total Cookie Protection offers strong protections against tracking without affecting your browsing experience," said Mozilla today.

"Total Cookie Protection is Firefox's strongest privacy protection to date, confining cookies to the site where they were created, thus preventing tracking companies from using these cookies to track your browsing from site to site."

By creating a separate cookie jar for every website, Firefox will automatically block any attempts to use cookies to track the users while they're browsing the web.

I'm not sure when/how this is supposed to be enabled by default...

I found, under Tools / Settings / Privacy & Security / Enhanced Tracking Protection / Standard
an "opt-in" checkbox to "Test pilot... Total Cookie Protection".

Assuming that's what they're talking about, I checked the box to enable it.

Since I run FF ESR, I don't have this enabled by default.

I have FF set for Strict instead of Standard, hence why I didn't see what you were talking about  ::)

Apparently the option to "Test pilot... Total Cookie Protection" under Standard Enhanced Tracking was only offered ["by invitation"] to some users (but not everyone)... I have it on some of my systems, but not on others.

If you weren't among those "invited" to test this, I believe it may have been included "as implied" among the Strict Enhanced Tracking settings [even if not explicitly mentioned there].

This all still begs the question about what exactly to look for once Total Cookie Protection becomes the general "default" under Firefox's announcement... how [and where] everyone can simply check to determine whether or not it's been implemented for them.

This is what I'm seeing under Strict in my versions (where the Test Pilot is included under Standard):
