Use CTRL+Shift+J to open the Parent process Browser Console.
Restart the browser using Ctrl+Alt+R.

Need to investigate whether this intentionally triggers some special behavior - the behavior of Firefox Enterprise here seems like expected?

Hello,
As a note, restarting using the Fx quick filter has the same outcome.
Thank you.
