Not exactly. I've a "work" container that retains my work-related sessions (on gmail, issue tracker, etc). So if I come back yesterday, I open a work container and I'm back to work.

Meanwhile, my personal container won't log me with my gmail/work account when I watch cat videos on youtube.

If I used facebook, I'd have a facebook-specific container. Just open a tab in it, and I'm logged in, but no cross-container tracking.

Also, history is retained, and all in one big pool (unlike having actual separate profiles).
