  • https://bugzilla.mozilla.org/show_bug.cgi?id=1372505 is now the #5 top crash.

Roundtable

[elan] We shipped the system add-on fix yesterday evening to 54 Release (thank you lizzard for the help) 55 is looking good; we are looking at content shutdown crash rate. Go/No-Go is going to be Monday. I know this is later than what we wanted. We are thinking 1-10% with WE support

• ToDo: Hold off on gtb RC1 Desktop until e10s-multi+webext decision is made

[marcia]

• FYI Google pushed out another beta of Android O (some reports say it is very close to the final version).
• https://bugzilla.mozilla.org/show_bug.cgi?id=1380896 seems bad - what else can we do? I have hit this on Mac and it appears it spans channels.

[mahe] Addressing screenshots issue with Giphy/Imgur site. Bug updated with metrics around the issue. Fix is mostly on the server side and doesn't need client change.
