the crash signature has been around for a while but it's visibly increasing in volume during the 56 beta cycle. a couple dozen affected installations are crashing hundreds of times during startup of the browser.

Comment 1

[Gerry Chang [:gchang]]

Track 56+ as this startup crash is increasing.

Comment 2

[Liz Henry (:lizzard) (privacy/fingerprinting team)]

Nicholas, can you help find someone to investigate since this is spiking dramatically in beta?

Comment 3

[Nicholas Nethercote [inactive]]

I will dup this to bug 1276488 because there is already some analysis there.

Comment 4

[Liz Henry (:lizzard) (privacy/fingerprinting team)]

Marking fix-optional for 56/57; while this shows as a top crash in beta it's a large number of crashes for only 20 installations. We can follow this in the duplicate bug.
