Why is Firefox HAR data page timings for onContentLoad and onLoad equal to -1
I am doing network performance test on my website to get timings of page load and resources. I can use the Firefox Dev Tools and "Save All As HAR". However, the data doesnt give the page timings correctly.
Here is the a sample of the HAR file:
"pages": [
{
"startedDateTime": "2017-07-22T14:47:49.001+01:00",
"id": "page_6",
"title": "Mid-Latency",
"pageTimings": {
"onContentLoad": -1,
"onLoad": -1
}
}
],
1. Why is the page timings -1 and how do I get the correct onLoad e.g. 800ms 2. Where is the waterfall resource timings that gives specific timings of scripts/images/css downloads, queuing and loading information?
