3rd Party Cookies in FF (SN 985)

[Russell...]

Correct me if I'm wrong as I'm doing this from memory BUT....... about two years ago when Firefox announced that they were isolating 3rd Party cookies from one another, thus eliminating their ability to track cross-site, Steve explained that his 'cookie forensics' web page showed that 3rd party cookies were still being accepted. Many people expressed concern that they were not actually being blocked as Mozilla had 'alluded' to. Steve said that it was because they were being held in their own 'cookie jar' and being prevented from being able to communicate with other cookies and gaining information about any other site than the site they come from, basically rendering them inert. Blocked, if you will.

Then SN 985 we've revisited the topic with Steve and Leo claiming that the "block third-party cookies" setting in FF doesn't work, seemingly having forgotten all of the above.

Am I missing something here?

Cheers. Russell.

I think your memory is basically correct, yes. I also think the wording in the Firefox UI is bad in they're using the word "block" to mean "defeat" and/or blocking the functioning of cross-site behaviour. If you read the "Standard" setting it says:

Standard

Balanced for protection and performance. Pages will load normally.
Firefox blocks the following:

Social media trackers
Cross-site cookies in all windows
Tracking content in Private Windows
Cryptominers
Fingerprinters

Based on this, I presume they're referring to their sandboxing with respect to cookies.

Hmmm yes. Thanks for that. I was wondering if something like Alzheimer's was taking effect(LOL). I recall that the original discussion also concluded that Mozilla's description was 'misleading' so to speak. Hence, on Steve's advice from back then, I have had FF setting set to 'STRICT'.
