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:
Line 10 in
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.
