Trying to make a self-signed XPI

I make some extensions for my own personal usage. Before, i used this command to build my extension so i could install in my browser:

web-ext sign --api-key=<userkey> --api-secret=<secretkey>

Now when I do this on my other extension, it won’t return an XPI like this document says it will:

" Signing your extension for self-distribution"

The command like program just infinitely signs the addon and eventually says that mozilla needs to review.

This is so frustrating!! I just want to make XPIs for myself!!!
