The Firefox implementation is passing 24% of the conformance tests at present, so maybe this is known? http://w3c-test.org/framework/results/nav-timing-default/ There are two things which I think would be helpful: 1. Verify whether we have a conformance test that covers this. I think we do not. Perhaps we could write one by inserting a large fixed delay in the beforeunload and unload handlers, navigating to a new page, and ensuring that the unload delay was counted but not the beforeunload. 2. Verify bugs are filed at https://bugzilla.mozilla.org/ for test failures (or file new ones). -Tony > > --Ricardo >
