Other Help Topics :: Can dsl do this?

Help!
I installed DSL to a pen drive
Boots good
I installed firefox then I changed the style
But when I reboot it is back to the begining all is gone
I have been reading on the forum about back up and restore do i have to do that everytime i boot??
is there a way to just boot to the clean style with nothing but firefox on the desktop? How do i do that on the pen drive.
Please help
