When starting Firefox I get this Error message below,  The same error 
message in /home/user or /root desktops when starting  Firefox.

I deleted /.mozilla folder in /home/user and put Bookmarks back in 
/.mozilla and still got the same Error message below.

Where and how do I fix this problem ??

Error Message;

your application's profile directory. Please check that this directory has no read/write restrictions and
your hard disk is not full or close to full. It is recommended that you exit the application and fix
the problem. If you continue to use this session, you might see incorrect application behaviour when accessing


I checked hard drive and it is not full, it has 75% free space in / and  /home
