[Alessio Placitelli [:Dexter]]

This doesn't seem to be a telemetry specific issue from the error message:

> INFO - Entering test bound test_sessionRestore
> INFO - Console message: [JavaScript Warning: "Empty string passed to getElementById()." {file: "chrome://browser/content/browser-sidebar.js" line: 301}]
> INFO - Console message: [JavaScript Error: "Error: Invalid sidebar broadcaster specified: " {file: "chrome://browser/content/browser-sidebar.js" line: 362}]

> INFO - TEST-PASS | browser/modules/test/browser/browser_UsageTelemetry_private_and_restore.js | We should not track unique domains from restored sessions. - 
> INFO - Buffered messages finished

There's no telemetry error here and the assertions on the values look good [1].

The error seems to come from [2]. Moving this to Firefox::General.

[:Gijs (he/him)]

This was a side-effect of bug 1391280 landing, and it got backed out, so this can be closed.
