cc'ing myself, gozala and Nicholas. While this isn;t a leak, the use of traits seems to cause egregious amounts of memory allocation. Traits is deprecated and has a logical successor so if it is causing issues we can bump the priority of porting various apis to use heritage. Also, if heritage uses less, the same or more memory, would be good to know that as well.
BTW, you can copy and paste the contents of about:memory; it's just text.
I looked for any trait.js usage in Aurora on OS X, the worst offender was a couple of MB: ──2,942,184 B (00.30%) -- compartment([System Principal], resource://transmission-web-helper-at-canuckistani-dot-ca/api-utils/lib/traits.js (from: resource://gre/modules/XPIProvider.jsm -> jar:file:///Users/jeff/Library/Application%20Support/Firefox/Profilesfirstname.lastname@example.org!/bootstrap.js -> resource://transmission-web-helper-at-canuckistani-dot-ca/api-utils/lib/loader.js:143)) I'm betting this is related to that add-on's use of the context-menu module, which has been reimplemented on master. Dietrich, anything unusual about your setup ( running the app for ages, etc ) that might allow these compartments to accrue tons of RAM? I installed memchaser and started logging, the memory usage of that compartment is currently: ─678,328 B (00.07%) -- compartment([System Principal], resource://memchaser-at-quality-dot-mozilla-dot-org/api-utils/lib/traits.js (from: resource://memchaser-at-quality-dot-mozilla-dot-org/api-utils/lib/loader.js:137)) Logging is enabled, and perhaps there is a steady memory leak as logging continues?

I recommend using your system's equivalent of top instead.
Summary: traits.js is 15mb memory for each instance → JetPack's traits.js is 15mb memory for each instance
