Pluto - Clear Stale / Deleted Notebooks

Pluto Notebooks work great with Julia. When Pluto opens, you may have a list of “stale” or deleted notebook.jl files which appear in list when opened. Deleting them from your computer won’t remove them from this list. The Pluto team have been asked for a feature to clear this list - in the meantime, I’ve found this method that works:

Let Julia open Pluto.jl in browser (localhost)
Firefox - Open Dev Tools (Ctrl + Shft + i) or (Right Click - Inspect)
Go to Console Tab -
at blinking cursor type: localStorage.clear()

This should clear the list.
