Used to work great, but now I can't see any of the text or check-boxes on the add-on window, so now I can't manage it. Please fix soon.

Hi Ricky,

Thank you for DF Yoube.

Unfortunately, it's causing below error logs in Browser Console. That's even for non-YouTube tabs.

view-source:moz-extension://my-local-UUID-here/scripts/background.js:16:
"Unchecked lastError value: Error: Could not establish connection. Receiving end does not exist."

Also, the feedback form from the extension itself most likely doesn't work. In Browser Console it logs: 400 BAD REQUEST for https://api.mailgun.net/v3/sandbox..../messages.

Need update most of the options not working.
