[ESEAVEY at TRANE.COM: FW: Iceweasel Random Crash While Running JavaScript]

Which ARM processor are you using? There have been some crashes on ARMv6
devices in the past. Some of them look similar to what you're reporting.
I believe the issues have been addressed but I don't know if they've
made it to a release yet.

It would also help (me) if you know roughly which Mozilla release your
Iceweasel build corresponds to.

Otherwise, I recommend that you file a bug on Mozilla's Bugzilla and
attach the relevant logs. (Feel free to assign it to me or put me on
CC.) This sounds like a Mozilla bug, rather than an issue with
integration into Debian. (I don't know the jurisdiction policies so I
apologize if this isn't the way things are done.)

Thanks,
Jacob
