I'm reporting this bug to investigate the spike and not necessarily to fix the crash in all branches. The following analysis focuses on Nightly stats since that's where the spike is. * Volume: #9 overall @ 1.49%, #4 for Windows 10 * Platforms: Windows 10 (100%) * Drivers: NVIDIA 353.62 (100%) * Devices: GeForce GTX 560 [GF114] (52%), GeForce GT 620 [GF119] (14%) * URLs: http://www.orange.fr/portail, http://www.spiegel.de/ are top of the list [Tracking Requested - why for this release]: crash appears to be spiking in Firefox 43.0a1.

OK, let's see what more data we can get.

There are still some crashes with this signature on 42 beta, but only 6 total on 43 for the last week. Milan, is this something your team might look at? Or, might it be related to bug 1189940? If not, I can untrack this since it's not super high volume.

I would like it to be the same as bug 1189940 (really, bug 1194335.) We won't have enough data for a few days, since the uplifts for the fix only went in on 10/19. Either way, we're not going to look at it until we get the data to either confirm or deny this being a duplicate of the bugs above.

Thanks Milan. I just realized this earlier today as I came across bug 1189940. I'll look back in a few days to follow up.

Do we have enough data at this point to know if bug 1189940/bug 1149335 helped?

Looks like only a few crashes now, and none on current branches. I think we can call it fixed for 43 by one of the bugs Milan suggested. In fact, fixed across the board seems correct.
