Firefox -createprofile “example” doesn't create profile [Centos 7.6]

Question

I am trying to create new profile via Terminal for firefox and am using this command:

firefox -createprofile 'profile'

It looks like everything is fine, but I can't find any new file by using ls | grep "profile"

While using

./firefox -profilemanager

Firefox is openning on blank page, by checking in help -> Troubleshooting information -> Profile directory, there is always same directory / name of folder.

By using

firefox -profile "profile"

the same thing happens.

I have tried to use uppercase version as well as lowercase; both work and open Firefox. What am I doing wrong?

I tried using firefox -P or -p , there is also no visual difference (as how is firefox acting, where redirecting and what profile applying)

Also by using ls ~.mozilla/firefox and opening with VI profiles.ini , I can see that there is only one profile there (which was created by default)

My current directory is /home/username/.mozilla/firefox.

-createprofile is not a valid command-line argument for starting Firefox. To create a new profile, you start by launching the Profile Manager by running firefox --ProfileManager. If you already have an instance of Firefox running (there could be an errant process running in the background; check this with ps -u) , you can add the --no-remote to start a new instance:

firefox --ProfileManager --no-remote

You can then start the Create Profile Wizard by clicking on the Create Profile button. This will create a new profile in ~/.mozilla/firefox/.
