After talking with Florian, we decided to disable the tests that are probably responsible for the failure in bug 1368364, so we can land bug 1242505. More details about the failure are available in bug 1368364.
Summary: Re-enable browser_BrowserUITelemetry tests on Linux Debug → Re-enable browser_BrowserUITelemetry tests on non-e10s
Discussed this with Paolo and our guess is that it's probably a bug in the test, not the browser code, and since it works on e10s which is our default configuration this is less pressing than I thought.
Priority: P1 → P2
