Hey guys, I got a question for all you fine fellas:

Would tracking cookies on one browser be able to detect what happens in another?

Today, no. Browsers don't share cookies, though they could if both vendors wanted to share, or one vendor bothered to "follow the other one around" as it were.



In 10 years, who knows.

Only if both are separate copies of Firefox and you copy the cookie sqlite database from one profile to the other.  I have to do that every time they update the "official" Firefox at work so that I can keep using my "unofficial" copy that actually lets me change settings

Well... you're not out of the woods.

In order to track people better - across domains, across browsers, and even if they delete their cookies, some places use flash cookies.  Those are stored globally by your flash player.  Many places will even put enough in them that they can rebuild HTTP cookies if you delete them.

So if you want to be safe, use the flash player settings manager to set it to never allow web sites to store data.

There's are also Firefox plug-ins that will delete flash cookies when it closes...(better privacy or privacy+)
