SiYuan web clipping for Firefox

I found Siyuan web clipper for Firefox:

• https://addons.mozilla.org/pt-BR/firefox/addon/siyuan/

I installed this addon in my Firefox e set the same parameters of Chrome:

SiYuan URL = http://127.0.0.1:6806

Token API = same code

However, when I tried save same webpage on Firefox appears the message:

Auth failed: for security reasons, please set [Access autorization code] when using non-127.0.0.1 access.

On the addon webpage there is this warning:

Please note that due to security settings, your Siyuan service must be https protocol. 请注意，由于安全设置，您的思源服务必须是https协议。

Someone could help me fix this?
