Test for privacy.thirdparty.isolate fails with a timeout
The test in dom/tests/mochitest/localstorage/test_localStorageByFirstParty.html
is failing with a timeout error.
In the logs we have:
1 INFO TEST-START | dom/tests/mochitest/localstorage/test_localStorageByFirstParty.html
JavaScript error: http://example.net/tests/dom/tests/mochitest/localstorage/firstPartyInner.html?domain=example.com&prescribed=test1&pref=0&host=http%3A%2F%2Fexample.com, line 10: SecurityError: The operation is insecure.
Line 10 in firstPartyInner.html
is:
found = localStorage.getItem("firstPartyTest"),
I think the reason might be https://bugzilla.mozilla.org/show_bug.cgi?id=536509 which now prevents localStorage access from an iframe when third-party cookies is disabled.
