Personally I have both working fine with hundreds of tabs, but chrome uses 5-10 times the ram.

Hmm. Maybe it's a FF add-on causing the problems for me, though I'm not using anything uncommon. An internal ps like chrome has might help pinning that down.

Chrome is definitely the RAM greedy one (and so many processes!), and always has been.

Firefox has "about:memory", which can give you some rather detailed information about memory usage.

Chrome has chrome://memory-redirect/

Strangely I can't find it in the latest dev release of chrome or chromium, it's still in stable. At least on linux, it also shows firefox's total memory usage, maybe they are doing lots of comparisons.
