1393390 - YouTube custom thumbnails literally take forever to upload

Status: RESOLVED DUPLICATE of bug 1383518

(Firefox :: Untriaged, defect)

Description

[oussama-studying]

Attachment: This is what happens on Firefox 55.0.2 when a custom thumbnail is uploaded to YouTube.

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:55.0) Gecko/20100101 Firefox/55.0
Build ID: 20170814072924

Steps to reproduce:

I tried uploading a custom thumbnail on YouTube, both during a video upload process and after editing its info and settings. Clicked on the "Custom Thumbnail" button and then selected an image.


Actual results:

The custom thumbnail upload process never ends. No error or crashes or anything, there's a spinning wheel that goes round and round for literally hours. I can't seem to fix this, even when I use different file formats. Clearing the cache doesn't help either.


Expected results:

The custom thumbnail should've finished uploading successfully in only a very short time, and it would be displayed where the "Custom Thumbnail" button once was.

The fix is on the way.
