[Chris Peterson [:cpeterson]]

This test verifies whether privacy.resistFingerprinting works correctly in Service Workers. In this test failure, all the navigator values are spoofed correctly back privacy.resistFingerprinting in the Service Worker except navigator.userAgent.

Is WorkerNavigator::GetUserAgent or Navigator::GetUserAgent not seeing the privacy.resistFingerprinting pref value in the Service Worker?

TEST-UNEXPECTED-FAIL | browser/components/resistfingerprinting/test/browser/browser_navigator.js | Checking default navigator.oscpu. - Got "Windows NT 10.0; Win64; x64", expected "Windows NT 10.0"

This test was running on (32-bit) "Windows 10 x86 2004 WebRender opt", so the only way navigator.oscpu should be returning "Windows NT 10.0; Win64; x64" instead of (32-bit) "Windows NT 10.0" is if resistFingerprinting mode is still enabled when the TV-fis job reruns the test multiple times.

That would probably be a test bug, the test forgetting to popPrefEnv() some temporary resistFingerprinting pref values.

This test is disabled for debug on 32-bit Firefox Windows. These TV failures are from opt on 32-bit Firefox.

[browser_navigator.js]
https_first_disabled = true
skip-if =
  os == "win" && debug && bits == 32  # fails on win10-32/debug

Comment 18

[Chris Peterson [:cpeterson]]

We test 32-bit Firefox on 32-bit Windows 7 and 64-bit Windows 10. This test fails on 64-bit Windows 10 because 32-bit Firefox's UA string reports "Win64" but the test expects a 32-bit UA. That's a test bug we could fix to handle this WoW64 case. This test would pass on 32-bit Windows 7. On 64-bit Windows, Services.sysinfo.get("arch") returns "x86" in 32-bit Firefox and "x86-64" in 64-bit Firefox.

This test intermittently runs (and fails) 64-bit Windows 10 because test-verify runs the test in a loop and some temporary pref changes might still set when the test runs the second time.
