Can't install firefox on Ubuntu

[dalb8]

I did apt install firefox

then

root@localhost:~# firefox

Command '/bin/firefox' requires the firefox snap to be installed.
Please install it with:

snap install firefox

root@localhost:~# snap install firefox
error: cannot communicate with server: Post "http://localhost/v2/snaps/firefox": dial unix /run/snapd.socket: connect: no such file or directory
