STR:

  1. Open Windows 10 Event Viewer.
  2. Start Firefox.
  3. Refresh Event Viewer.

Two DCOM 10016 warnings appear:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID 
{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}
 and APPID 
{15C20B67-12E7-4BB6-92BB-7AFF07997402}
 to the user <USER> from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). 
This security permission can be modified using the Component Services administrative tool.

The CLSID and APPID correspond with the RuntimeBroker. More of these warnings appear when visiting sites that have videos such as youtube.

Regressed by Bug 1521370.

I've been getting these ever since I updated from Windows 7 Pro to Windows 10 Pro which was 1903 at that time (now 1909). I thought it was just some Window 10 issue due to the upgrade over Windows 7 and went through all kinds of things to fix it. Event 10016 seems to be a common thing when Googling it.

But, yeah, I can reproduce this with Firefox 72.0.2 and previous versions.

Hi, jya,
Any thought about why bug1521370 causes this issue?
