[xubuntu-users] disappearing thunderbird settings

[Norman Silverstone]

Continuing with my task of setting up Thunderbird I created a number of
sub folders to inbox and set up message filters for them and all was
working as it should. I needed to re-boot my PC so I closed Thunderbird,
re-booted and re-opened Thunderbird only to find all my settings had
disappeared including several emails. Can any one tell me what I could
have done wrong, please?
