Backup in Thnderbird 3.1.8
I am using OpenSUSE 11.2 and have installed Thnderbird 3.1.8.
Now the problems are :
In my office , where Ubuntu is being used, I've also installed Thunderbird, and my Yahoo ! account works smoothly there, but not in my OpenSUSE 11.2 machine.
How can I take the backup of my any particular account of Thunderbird ?
