Data corruption/crash bug in Firefox for armhf

Hi folks, As a heads-up, there's a long standing bug in the way Firefox handles register assignment in XPCOM for 32-bit ARM: https://bugzilla.mozilla.org/show_bug.cgi?id=1050258

The symptoms are random data corruption and crashes.

(details of bug and fix in the link above).

Whilst upstream go through the motions of getting this fix merged, I would encourage you to pull in the fix for now into your packages (or at least keep an eye on this bug report).

Cheers, -- Steve
