Ubuntu 11.04: I have been getting this message whenever I install Firefox from the repositories and downloading the tar file. I cannot use Firefox! " There is no Profile folder Could not initialize the application's security component. The most likely cause is problems with files in 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 security features."Firefox does not respond to any addresses or a google search. Indeed it responds to nothing. There is no Profile folder!
