phpMyAdmin CSP Error in Firefox

I have a trouble starting phpMyAdmin in Firefox after fresh HestiaCP installed:

F12:
Content-Security-Policy: Ignoring “‘unsafe-inline’” inside script-src: nonce-source or hash-source specified index.php

Content-Security-Policy: Ignoring “‘unsafe-inline’” inside script-src: nonce-source or hash-source specified index.php
Content-Security-Policy: Page settings blocked execution of an inline script (script-src-elem) because it violates the following directive: “script-src ‘self’ ‘unsafe-inline’ ‘unsafe-eval’ ‘nonce-bW96LWV4dGVuc2lvbjovL2JkNTNhMzIwLTlmZGEtNDQ3OC05Zjk2LTJmM2E2ZTAxODFmYS8=’” index.php:53:53

​phpMyAdmin works fine in Google Chrome and MS Bing.

I solved the problem by installing the Disable CSP and CORS extension in Firefox, but maybe there is a better solution?
