I wonder whether somehow you have ended up with some files/folders
with root permissions.  Perhaps you ran firefox with sudo or
something.  This will set all files in your home directory back to
being owned by you (which is what you would normally want).  If your
username is udvarias as it seems from the post then
cd ~
sudo chown -R udvarias:udvarias .
Note there is a dot on the end.
If you only wanted to change the permissions for the profiles then cd
~/.mozilla/firefox rather than cd ~
