Chromium vs Firefox?

Firefox should not only optimize closed tabs, but open tabs as well 
since they introduced Panorama in version 4. Panorama is a surefire way 
to make people never close a tab, just hide it. Tabs become like half 
loaded bookmarks, and I like the idea.
The last time I used Panorama with 7 groups and 34 tabs, Firefox was 
eating 1.2 Gbyte memory on a 2 Gbyte Windows 7 system with an open 
Virtualbox virtual machine with dedicated 1 Gbyte memory. Swapping hell 
just began.
When I restarted Firefox, memory consumption dropped down to "only" ~500 
Mbytes.

A few dozen open tabs won't hurt Chrome that much, although this in 
itself is not enough for me to ditch Firefox in favor of Chromium.
