Weird is that the test isn't failing: $ mach test devtools/client/netmonitor/test/browser_net_server_timings.js

Harald, does it work for you?
Do you have an online test case?

Just a guess, might those errors that recently started showing up in Browser Console be related?

@Alice0775 White, thanks for the regression window!

@Matt, it looks like nsITimedChannel.serverTiming isn't available in all cases after bug 1583700.

Here is the place where DevTools is consuming the field

Can you please look at this, thanks!
