Feedback Link in Firefox 57 Throws Unhandled Promise Rejection

Everytime I try to give feedback in Firefox via the link on the page edit screen the following error occurs.

I am using a modified users.js file.

Does anyone know the Firefox preference to prevent this error?

Unhandled promise rejection

Jason,

Can you let us know what changes you made to your users.js file? I can confirm the error does not occur when using FIrefox 57 out-of-the-box.

Regards,

Shannon

I use a modified ghacks users.js file below.

Thank you, Jason.

I've shown this to the editor team and they did let me know that customizations such as this, ad blockers, etc. can and do break things in Cloud.

Please continue to provide your feedback via Community. If you're able to isolate the problem with your script you can let us know and we can make a post here that the feedback form does not work with certain user scripts so other users are aware.

Regards,

Shannon
