Comment 13

[Mark Banner (:standard8)]

The errors all seem to be:

Unexpected modules loaded during content process startup: resource:///actors/RFPHelperChild.jsm

Bug 1553384 was the last one that touched RFPHelperChild.jsm relating things, but it landed around 10 days before the big spikes started, so I'm not sure that's it, but I'll move the NI across to Neil in case he has any ideas.

Comment 14

[Neil Deakin]

The RFPHelperChild.jsm module is initialized only when a resize event occurs. These failures suggest that a resize event is firing during startup in some situations. Perhaps some other change has made the resize event occur earlier sometimes, but only on Windows. There was a Windows-only resize related change on October 1 in bug 1581942. Might be worth investigating that or other changes around then.

The easiest fix though might be to just add the module to the intermittent list in browser_startup_content.js
