No guide necessary: if you use the startup disk creator to make a USB stick
with Trisquel, just check the box for "when starting up from this disk,
documents and settings will be stored in reserved extra space".
Alternatively, you could copy your browser settings from
Home>.mozilla>abrowser to a separate USB stick and restore them manually.
If you are using Evolution for email, your data is in home>.local>share
For a modern, updated browser, just open a terminal window and type "sudo
apt-get update" and when it finishes, "sudo apt-get install abrowser"
