Steps to reproduce:

Actual results:

Dev Tools > Network tab content is empty. No network request can be recorded or managed.

Expected results:

Dev Tools > Network tab content shall not be empty. Tools to record and manage network request shall appear in the view.

Must be a recent regression, Alice, can you find it for us please.

Flags: needinfo?(alice0775)

Thanks you, Alice, nothing really obvious here.

Julian, there are a few devtools changesets in that range. Anything comes to mind that would have broken the network tab in TB?

Manually adding devtools.netmonitor.features.requestBlocking = false will fix the issue on TB71a1.
So. this is regressed by d9b4b368aa2e7151f0a1dd8065a0864bc4d001e6 David Walsh — Bug 1580530 - Implement NetworkActionBar in the netmonitor r=Honza

Interesting. So does FF set this pref? Oh, yes, they do here:
browser/app/profile/firefox.js
2107 pref("devtools.netmonitor.features.requestBlocking", false);

So we just need to port that. Thanks so much, Alice, I'll do that in the next two hours.

FYI, the preference option devtools.netmonitor.features.requestBlocking is non-existent by default in TB. See attached...

Adding it manually as a boolean preference with value false did not fixed the issue at my end...

Attached image requestBlocking=false not fixing issue (obsolete) —
Attached image browser.toolbox.conectiion.status (obsolete) —

FYI, after a short while the DevTools > Network tab disappear and is replaced by the Browser Toolbox connection status attached...

This does fix the issue. Richard, you can confirm in tomorrow's Daily.
