Comment 1

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

This affects 40-50 browsertime performance tasks (and shows up even for successful tasks). Is this risk for users, and can we get rid of it in CI?

Comment 3

[(No longer employed by Mozilla) Aaron Klotz]

It's not a security risk, given that it's a null pointer. But something worth investigating and fixing, of course.

I think we probably need to look at the original dump to figure this one out, unfortunately. The call stacks give a hint but I don't think there's enough there to give us a smoking gun.

Comment 7

[David Lawrence [:dkl]]

Moving all open Core::Widget: Android bugs to GeckoView::General (then the triage owner of GeckoView will decide which ones are valuable and which ones should be closed).

Comment 8

[[ex-Mozilla] Agi Sferro | :agi]

This should be fixed now.
