Can't restore firefox settings with .mozilla backup

Use ls -al to show hidden files

Your permissions look OK

I looked around a bit.

  1. How did you copy the .mozilla directory?
    cp -r may not preserve everything
    they recommend cp --archive to preserve links and permissions
    or use tar

  2. It would seem the only bjt you really need from your old system is the firefox profiles. They are in
    `~/.mozilla/firefox
    so maybe you should just overwrite that bit after you let it start up.

It is quite annoying. All the firefox and thunderbird info refers to Windows. There is nothing relevant to Linux.
