I still haven't been able to reproduce. Philippe, are you sure you're seeing a negative domainLookupStart-fetchStart? I do see a negative connectStart-domainLookupEnd in some cases when reading from cache; I filed https://bugzilla.mozilla.org/show_bug.cgi?id=819685 on that. One other note: Given DNS prefetchers, I'm not sure the restriction that domainLookupStart must be >= various other things actually makes sense.... > I don't think you can assert that domLoading >= responseEnd as this test > does.
