It's #30 top crasher in 12.0a1 and happens only with 64-bit builds.

[Wayne Mery (:wsmwk)]

pretty rare now. only 4 crashes per month for FF14 and FF13. ANd all are x86. bp-fa96e28a-aa24-4e6a-8ef0-30b7e2120804

perhaps the signature has changed?

[Andrew McCreight [:mccr8]]

This doesn't look like a problem any more.  The signature may have just changed.
