Doesn't work, and the "Update" button that is supposed to display the python bytecode freezes the IDE.

It's not clear to me how to actually view any bytecode with this plugin. Also the developer website has HSTS enabled but an invalid self-signed certificate which prevents Firefox from loading the site. There's no user information on the GitHub either.
So how do I use this?
