How does your posting of terminal output help the OP? If you're going to post stuff, at least explain to the OP how this will help him/her resolve their problem

Ok, to clarify:

- Trying out Fedora 13
- Using Firefox
- Installed Firefox Sync plugin
- Firefox sync plugin does not sync

So... My first task is to get Firefox sync working. I have created and use a sync profile on other machines.

Talk of permissions is perhaps a red herring - I might need to change some config files to enable sync to work, hence the initial request.

Are you getting any error messages?
Are yo behind a proxy?
Do you know what you need to change?
As told in previous answers, open a terminal, become root and change the files.

I don't know or use the "Firefox Sync plugin" but if this is something that synchronizes data with a remote host (website?) then it will use either port TCP/80 (HTTP) or port TCP/443 (HTTPS).
- As far as I know the default firewall configuration does not restrict outbound traffic. If you somehow still suspect this to be a firewall issue, and if you modified firewall rules, then you should check 'em or use "-p tcp -m tcp --dport -j LOG" lines in your outbound chain to prove for yourself traffic does or does not pass.
- As far as I know the default SELinux targeted policy configuration does not restrict the plugin from working as the unprivileged user. If it does then 'setroubleshoot' should display an error or else there should be related AVC messages in /var/log/audit/audit.log you could 'grep' or 'ausearch' for.

I am not sure if it is about this

Normally a mobile phone is synchronized with an OS and not only a browser but repo might be right

For the login screen some versions and distros have special knobs at the desktop menu called users/groups and similar
There are checkboxes for login for root, admin and so on
The minimum login ID has to be set to 0 for normaly root ID is 0
But it might become 7777 in future
And for more explanation: first non-root user might become 10,000+
But I can also imagine chars, neg numbers (lol for lot of light)

I have to say further I haven´t used login command before just the Xserver desktop environment menu users/groups button at CrunchBang 8 (Ubuntu based) and that worked for me

The smaller LiveCD might be limited and is also available for several desktop builds at http://fedoraproject.org/de/get-fedora-options#desktops

Furthermost I have to add that I have no experience to sync a mobile phone with a computer nor any knowledge about linux OS on mobile phones
and if the browser crashes it simply crashes mostly by overload, no swap, little ram and such like.
I decided to have a short look on a distro and when its getting difficult than let this version be because there often is more to come!
I think I`ll stay with *Pup* 4.3.1 for 5. is said to be Ubuntu based.

All the best and much luck!
