Cookie Persistence Issue

I am almost certain that Firefox (and all other major browsers) shares cookies across tabs. In fact there are a number of posts on other forums asking for how to configure Firefox to not share them:

I think it would be interesting to capture a browser trace of the failure to see what's happening. I expect the issue is not that the browser uses separate cookie stores per tab or window.
