1595191 - Fix intermittent hangs in browser/components/extensions/test/browser/

Status: RESOLVED DUPLICATE of bug 1594572

(Core :: DOM: Content Processes, task, P3)

Description

In bug 1580212, I set dom.ipc.keepProcessesAlive.webIsolated.perOrigin=1 in browser/components/extensions/test/browser/, to work around very frequent intermittent hangs and leaks in that directory. We should fix whatever the causes of that are and drop the pref change. Bug 1594572 is one observed source of a hang in that directory, but there might be more. I don't know if the leaks and hangs are related or not.

I'll split out the leaks into a separate bug, on the assumption that they are probably unrelated.

Andrew, do you think these intermittent shutdown hangs need to block the Fission mochitests milestone (M4.1)?

Same reply as bug 1595190 comment 2.

Tracking for Fission riding the trains to Beta (M7) after we see how much of a problem this is with more users.

Andrew, could you please remove the pref and try to repro the failures again?

It looks like kmag fixed this hang and removed the pref in bug 1594572.
