Is there a browser build or plugin extension that has a separate cookie jar for each tab that follows the tab?
My ideal browser has zero persistence and each tab maintains its own cookies. Links opened as new tabs would share the parent's cookie jar, but separate tabs loaded to the same page could both be logged in at the same time.
Keep in mind that cookies are just one of the many "storage backends" that websites can potentially use to track you.
There are stealth techniques such as browser cache hits, browser configuration fingerprinting, and even system clock drift, that can track you beyond cookies.
You would need a separate browser profile or even a separate OS for each tab (see Qubes OS) to be on the safe side.
> Each group of tabs, separated by color, is its own browsing session with its own cookie jar
Yes!
> Log in to one web site with many accounts simultaneously
Yes!
> Use with Mac OS X or Windows
No!
Would need a Linux build as well (actually that's the only one I need). Otherwise, looks cool though and will be keeping an eye on it. Thanks for sharing!
