Hi everyone, I tried to upgrade from xubuntu 13.04 to 13.10 on my Asus eee 900 but it didn't work at all, so I decided to switch to Lubuntu 13.10. The system now is far more responsive, up and running after only 15 seconds from the power on.
However, I exported the whole home folder from the old xubuntu installation and then I imported it in the newly installed lubuntu. When I try to open Firefox, an errore message says it is impossible to load user's profile, while thunderbird doesn't load at all. Is it just a problem with the folders' permissions?
I'm not a linux expert, so I'd appreciate an answer for dummies

Thanx everyone for your help!
