User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0
Steps to reproduce:
- Open devtools network panel and put filter
dmp
- Open https://www.europe1.fr/direct-video
- Click CTRL-R several times and observe network resources info. Compare this with network data from another source (proxy like Fiddler) and with data from ResourceTiming APIs.
To obtain ResourceTiming data, use the following in the console:
cd(document.querySelectorAll('iframe')[1])
performance.getEntriesByType("resource").filter(item => item.name.match(/dmp/))
(Note: You need to execute the two lines separately one by one for cd
to properly change the console context to the iframe)
Actual results:
Sometimes the data in devtools UI is incorrect - see the screenshot (some resources are marked as 200 while are actually 304, and the transfer size is totally bogus).
This might be perhaps related to bug 1561532 and race functionality in general.
For info, I have network.preload
= false
in about:config

@jakub: can you please come up with simple test case we could use to investigate the problem? E.g. is there an online page that always shows the problem?

Clear a needinfo that is pending on an inactive user.
Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE
