You need an entry in /etc/hosts for each display name in `xauth list`.
Look at my /etc/hosts:

```
$ egrep '^[^#]' /etc/hosts
::1 localhost localhost.my.domain
127.0.0.1 localhost localhost.my.domain dtxdf-laptop
```

After adding an entry in the specified file, you must remove or rename
your profile application (~/.thunderbird or ~/.firefox):

```
mv ~/.thunderbird ~/.thunderbird.bak
```

This is necessary because your hostname will remain in the cache.

Now, just run firefox and it should be fine.
