for each...in is deprecated: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Statements/for_each...in I'll write a patch to stop using it.

Hm, Fabrice, what gecko were you running that led to this problem? I can't actually reproduce the error on today's mozilla-b2g18 on my phone, or on the latest mozilla-central B2G desktop (I don't have a current m-c build for my phone). I can still write a patch to fix this, but I'm curious why I'm not seeing the problem. Also, I searched Gaia, and we also use for each...in in one place in browser/js/browser.js, so we should probably fix that as well.

https://github.com/mozilla-b2g/gaia/commit/5aafc8832854b26d9dc50163e9a785f177a69dc2 I filed bug 824101 about removing for each...in in browser.js. But I'm still curious why this only caused errors now.
