On .LAN domains, how to stop firefox switching to https (when it's not available) and stop complaining about self-signed certificates when it is available ? (lemmy.ml)

I'm just so annoyed of fighting this all the time.

If I can't figure this out I'm going to disable all https redirecting and all certificate errors off so I can have some peace

EDIT: I do not wish to manage certificates I do not want to setup private key infrastructure I don't want to use real internet domain names I don't want to manually install certificates into browsers after fishing them out of my ephemeral virtual machines

I just want to, add exception for *.lan for https auto redirect and auto-accept self-signed certificates as valid. This is not much to ask.

Pretty sure there's not a per-domain setting for that. If you have HTTPS-Only Mode turned on in the settings it will always try to use HTTPS first and present a warning before switching to HTTP.

If you want to continue using HTTPS you can setup your own CA certificate to sign certificates for your .LAN domain names. All you need to do then is add the CA certificate to your trusted certificates in Firefox and the signed certificate to the device hosting the HTTPS service.

EDIT: TIL there an exclusion feature. Neat. I didn't see this on Firefox for Android though. https://support.mozilla.org/en-US/kb/https-only-prefs
