Florian, could you help us assign this to someone?
Thank you.

Comment 10

[Florian Quèze [:florian]]

This is a regression from bug 1613705, and the frequency increase is due to bug 1665318 that made the platform code run faster, and the race more likely to cause trouble.

The tests use a promise based on a mutation observer to detect when about:processes has been updated, but now the promise is sometimes resolved by DOM mutations triggered by l10n. Bug 1613705 tried to workaround the issue using waitForCondition calls, but that's not a good solution.

I sent a tentative patch to try https://treeherder.mozilla.org/jobs?repo=try&tier=1%2C2%2C3&revision=ab039357cb2275daf3cadd46360647a9185d693e

Bug 1709752, bug 1724643 and bug 1728304 are the same issue; we can close them as duplicate once this bug is fixed.
