Has anyone else faced the issue, that about:config resets all changes made on a daily basis? I use AdGuard for Android, which performs HTTPS filtering via a local VPN. Since Firefox handles certificates differently that all other browsers, I'm forced to use the beta branch, where I can access the about:config menu. There I can set security.enterprise_roots.enabled to true. Unfortunately I have to keep setting this feature on a daily basis, since it resets every night.
