Not sure why this error happens, but I'm observing it locally in Nightly in the Browser Console.

Any ideas on how you trigger this? I can't replicate: but I do get other RFPHelper errors (which don't seem material)

The severity field is not set for this bug.
:enndeakin, could you have a look please?

Problem.
I see the error in my local mochitest of C-C TB and it happens near the beginning of various tests, meaning no tests are performed at all.
To wit: There are a few locally added debug dump lines.

Compared with the earlier mochitest runs, it seems that mozrunner (?) is not responding.
Something seems to be amiss, but not sure what exactly.

I refreshed the source trees M-C, C-C and build C-C TB using gcc-10.
Now mochitest runs without this error. The log from the successul run where previously the error occurred is like this.

Either it is a timing-dependent issue or there can be a logical flow that is triggered under certain unknown conditions.
