>Environment:
I don't have the uname -a output, as I'm entering this from the live DVD of another OS. However, it was installed and patched up to 7.0.1 yesterday (September 22, 2016). going by memory, the output would otherwise include:

NetBSD 7.0.1 amd64
>Description:
When I boot up Firefox, it hangs and then crashes within one minute. I started it from within twm with:

$ firefox &

As Firefox started and then crashed, the originating xterm session generated this output:

I'm not the most technical user, so I don't know entirely what to make of the above, though I suspect there are some solid clues in there for those who can.

Cheers,
James
>How-To-Repeat:
In this case, simply reboot Firefox.
