The Inquirer reports that apparently Dell UK ships new computers with Mozilla Firefox pre-installed.
A slashdot-commenter seems to confirm this:
My sister got one of these, to my surprise, the fox was there.
There is an icon on the desktop, along with Internet Explorer's and about 30 others. I believe Internet Explorer came as default, but I didn't observe the first seconds directly.
It seems a standard install, no obvious branding or skinning - the start page has been set to Dell's EULA.
Neither browser masks the other that I can tell, of course each has it's standard 'I'm not the default' message.
