@jgbarah So I don't need to use a different browser on each site? no more konqueror for amazon, chrome for mastodon, firefox for FB, opera(oh sht they use the same stuff as another now?) all with incognito? hmm I think I'll keep doing that

@jgbarah

A furry blue muppet would like a word.

@jgbarah Hmmm, might have to start using it again.
@jgbarah They just had to abbreviate it TCP huh 🙄
@jgbarah is this the final rollout? I think I have been reading the same news for years.

@arshubham They've been rolling it out gradually for a long time - I suspect the fear was that this might break enough websites that it would be a problem for the average user.

The article says this is for "all users" now.

@jgbarah @cr1901 heh, I implemented a similar anti-tracking approach in WebKit in 2013 that was meant to defeat trackers that cached unique IDs in images they'd read back. I made it so that the cache was partitioned based on origin, so these cache-based trackers would be able to coordinate.

@jgbarah This is definitely a step in the right direction. Glad to see Firefox implementing this additional protection.
@jgbarah This is how cookies should have worked from the beginning.

@jgbarah

Minimize that by fixing this setting:

*Type about:config in address bar
*Search for privacy.resistFingerprinting
*Toggle it to "true"

@jgbarah the cookie values are still supplied by the remote sites, how does this stop them from correlating and tracking individuals anyway?
@gws
In general, they cannot, because cookies in different "jars" seem to correspond to different browsers

@jgbarah Even with all the ups and downs Mozilla has gone through, I still don't grok why the rest of us don't get on board and support the projects that they're doing?

As someone in the WordPress space, I see almost every single initiative that Mozilla is pushing being spoken about or attempted in our space. But I've rarely (ever?) seen reference to what they're doing.
