Unable to delete add-on in developer hub, script errors on page

I have an unpublished add-on that I want to remove. However the “Delete” button does nothing.

https://addons.mozilla.org/en-GB/developers/addon/trello-markdown-descriptions1/versions#delete-addon

I guess the script error, that appears when the page is laoded is the cause of this:

Uncaught TypeError: r.getAttribute is not a function

Hey @pke. That’s a curious error. I just tested the add-on deletion flow myself and didn’t encounter the issue you’re describing. I also didn’t see the Uncaught TypeError you mentioned on page load.

Here are a couple of ideas on things you could try:

  • Check if you have JavaScript disabled by visiting about:config and searching for javascript.enabled (support article).
  • Try clearing your browser’s cache, reloading the page, and going through the deletion process again.
  • Try deleting the add-on from a new session in a Private Window or in a different profile.
  • Try deleting the add-on using a different web browser or a different device.

Thanks for testing. I am doing this in a vanilla fresh Firefox installation. So all your tips I already tried.

Maybe someone from the Add-On team can just delete it.
