these content crashes are starting to appear since april 11 from 32bit installations on windows 10 - all with cpu info "GenuineIntel family 6 model 122 stepping 1" (these are entry level intel gemini lake processors).
since the signature isn't showing up anywhere else than on 66.0.3 yet, perhaps it's just a build-specific issue...

I don't see anything relevant in:

https://hg.mozilla.org/releases/mozilla-release/log?rev=FIREFOX_66_0_2_RELEASE%3A%3AFIREFOX_66_0_3_RELEASE

Comment 2

[Emilio Cobos Álvarez [:emilio]]

Seems win32 only, maybe a miscompilation?

Comment 4

[Daniel Holbert [:dholbert]]

Dropping to S3, given low crash volume.

Comment 5

[BugBot [:suhaib / :marco/ :calixte]]

Closing because no crashes reported for 12 weeks.
