[BUG] User not found

[m0lDaViA]

First, i didn't tested that on anything else then flaticon.
On flaticon you can't download because the user object is null.
That happens because the load event isn't triggered because the manifest says document-idle.
But at that time the load event is done, therefore there is nothing to run.

Switch to document-start and add a mutation observer OR a small timeout for the head append and you're fine.
