http://ubuntuforums.org – Hey. I'm really sad with what just happened. I deleted all the hidden files :( I though it was some files from some previous installation that I made. I tough it was garbage. But then I remembered it was the hidden files... How can I restore them? Ubuntu didn't even create new ones. Now I've lost all the firefox favorites and for example the bashrc .file Please help me. (Hardware)
