[Description:]

[Environment:]

Windows 10 / 87.0a1 2021-02-19
not reproducible Mac 10.14.6 and Ubuntu 20.04 / 87.0a1 2021-02-19

[Steps:]

1. New profile.
2. Start up Firefox.
3. Open about:config:
   set app.normandy.logging.level to 0
   set browser.search.log to true
4. Close and reopen the browser.
5. Open browser console (Ctrl+Shift+J)

[Actual Result:]

Blank browser console.

[Expected Result:]

At least the logs for search and normandy should be listed.

[Regression Range:]

Bug 1642599 - [devtools] Enable all console messages server support everywhere. r=ochameau.

Bug 1642599 should be backed out and revisited. This breaks console resources for content process targets.
That's because resource-available-form event isn't declared on content process targets:
https://searchfox.org/mozilla-central/source/devtools/shared/specs/targets/content-process.js#35-43
Registering the events will highlight more work because bug 1642599's patch will spawn duplicated messages as per:
https://phabricator.services.mozilla.com/D103285#3357864

The missing resource-available-form event on content process target specifications
break console resources for content process targets.
Adding this event will probably create duplicate and so requires some more analysis.

:ochameau, since this bug is a regression, could you fill (if possible) the regressed_by field?
