I've started with an installation of Firefox 17.0.6 ESR on 64Bit Windows 7 and set the bookmarks bar the way I want.
I've used the 'Export Bookmarks to HTML' option and stored the file as 'bookmarks.html' in the c:\program files(x86)\Mozilla Firefox\default\preferences folder
When I create a new user on the machine, that user just gets the default 'Most Visited' and 'Getting Started' links.
I'd prefer not to have to use the CCK as I've had some issues with it in the past for upgrades.
If it was possible to ALSO have the bookmark bar shown on startup for new user, that would be extra awesome.
Thanks all, Chris
