Hi frinds !
I m a newcomer in Linux world.
I have just installed Ubuntu 13.04.
On some website I read about Firefox20. So I want to upgrade my firefox. But in help there is
one step in that I have to move firefox directory ( which actually came after extracting file firefox-21.ob7.tar.bz2)
to /opt folder. For that , 1st if u have previous firefox version remove it by following command :
sudo rm -r /opt/firefox
and then move firefox directory to /opt with follwing command :
sudo mv firefox /opt/firefox20
But in both the cases I got error like there is no such file or directory.
So I tried manually but I think there is no copy/cut paste option in /opt. ( I saw /opt properties and got
following message :
" U r not the owner so u can't change the permission "
So can anyone help me in installing firefox20 ?
Thank u in advance.
