This crash appeared relatively non-existent until October 12, 2013 and is only showing up in large volume in Firefox 25.0b7. It's currently at #199 in Firefox 25 Beta.

Nothing stands out to be in the pushlog:

Since these are happening on Windows only is it possible this is a manifestation of the intermittent PGO issue?

Alex, I'm need-infoing you to put this on your radar for Firefox 25. I'll continue to monitor it over the coming days.

Thanks, let me know if this rises at all. Might be a one-off, as you suggest

I'm not seeing any instances of this signature for Firefox 25.0b8 or 25.0b9. Calling this WORKSFORME.
