resolv.conf does not take effect

Whatever I type on `resolv.conf` I still can resolve domain name on `firefox`, so it seems to stay on the old configuration

I want it to listen on the local `dnscrypt` server, how to make effective `resolv.conf`?

Are you in the United States?

tl;dr: go to about:config and set network.trr.mode to "5" to disable DoH.

Re: resolv.conf does not take effect

Is the issue limited just to firefox i.e. everything else uses the server configured in resolf.conf?
Please also use code tags for file contents,  commands and their outputs.

Re: resolv.conf does not take effect

`dig` seems to stay up to date, but I don't know if he uses `dnscrypt` or not, just that he doesn't resolve if `resolv.conf` is not valid (`parse of /etc/resolv.conf failed`)

What is a code tag? What file contents are you talking about? What commands? I writed the outputs up here

See the bbcode it helps formats output as seth used in post #4.
With an empty resolve.conf does the host command fail to resolve hostnames?

Re: resolv.conf does not take effect

With an empty `resolv.conf` both `dig` and `host` can resolve hostnames

Re: resolv.conf does not take effect

In firefox -> Preferences -> Network Settings is a proxy enabled or is DNS over HTTPS enabled?  If you create a new firefox profile can it still resolve hosts with an empty resolv.conf?

Re: resolv.conf does not take effect

System proxies are used and nothing is ticked

`firefox` still resolves queries with a fresh profile

Re: resolv.conf does not take effect

If you disable system proxies is the result the same?
To start the firefox profile manager from the command line.

firefox -P

Re: resolv.conf does not take effect

With "no proxy" it's the same

`nmcli dev show | grep DNS` shows the old DNS configuration

Re: resolv.conf does not take effect

What domains do you try to resolve? You've the mdns responder in nsswitch which will likely resolv all *.local domains.
Does "drill" resolve domains w/ an empty resolve.conf?

Please change your topic title to something that actually describes the problem you have: https://wiki.archlinux.org/index.php/Co … ow_to_post

Incidentally, are you still running Manjaro?
