@Marco, according to the regression range in comment #1 I don't see commit related to [devtools-html] so, should this really block bug 1263741?

[Bas Schouten (:bas.schouten)]

This is most likely just the child process not dying or being killed for some reason, probably to do with debugger related IPC? I doubt this is in any way graphics related.

Comment 5

[Joe Walker [:jwalker]]

This bug has a priority set that is not P1, so it's not an urgent fix.

Comment 6

[Milan Sreckovic [:milan] (needinfo for best results)]

Joe, can you set the tracking flags for 49, 50, 51 as appropriate?

Closing because no crash reported since 12 weeks.
