I'm not aware of any recent changes. Though, I also didn't touch this code recently. I know that :arai changed how the interaction flag is handed through Promises in Bug 1732953. This is the origin of the test. Looks like the error being thrown is a result of trying to recover from a crash: https://searchfox.org/mozilla-central/rev/81c52abeec336685330af5956c37b4bcf8926476/browser/modules/ContentCrashHandlers.jsm#292 The crash could come from failing to create a process, I can see an error message about that in the logs: The OSError is very suspicious, perhaps a Windows Defender false positive on our test machines?
