I did warn on that page:

Still, yes, Chromium uses more memory. A good part of this is because per-process tab. Once Firefox get the same per-process tab architecture, it will be easier to compare both browsers together.

Yep, Chrome / Chromium are now the #1 reason to bump my ram to 16GB. While using a laptop for coding / VMs etc. I still find my browser eating more ram most of the time - it simply doesn't handle paging out gracefully, and is horrific for my uses with < 4GB ram on any OS.

well, firefox seems set to use a process for UI and a process for all tabs (such as in nightly right now), the consumption is still far lower.
