What was your original profile ? I mean what qualities did it have that the alternative doesn't? First note you can save the profile, so in future you can always use it. I have the same one for decades, even though new installs, on new computers will start afresh. There is a file called [profiles.ini] that dictates the profile in use. Type [about:profiles] in the address/url bar to see what you have. You will notice in the default there are two copies one in Local and the other in Remote.
