Specifically the "By not charging, we mean the Mozilla product must be without cost and its distribution (whether by download or other media) may not be subject to a fee" part.
Granted, I think charging $18 to install a browser is entirely dickish behavior, but the legal nuances of ‘distribution’ versus ‘installation’ are neither subtle nor vague.
It's pretty clear (to me - IANAL) that Dell is using Mozilla's trademark without their permission. If they called it Open Source Pre-Install Service, and explained that it includes Mozilla Firefox and some other software, I think it would be fine.

This is unfortunately worded in Dell's favour, as any trademark policy from Mozilla will stand independently from the license. Furthermore, Dell is allowed to use Mozilla's trademark in a fair way, regardless of what their own policies say.
In this case, the process of ensuring that a functioning version of Firefox resides on the machine involves:
1. Transferring the Firefox software to the machine
2. Explicitly preparing the machine so that the Firefox software can be run (in this case, installing Firefox)
The Policy only applies to the first item. No part of the policy refers to the second action, and it's fair game for Dell to charge a fee for the labor associated with installing the software (they cannot, of course, charge a fee for the part of the process where the software is distributed to the machine).
If this sounds like nitpicking, welcome to the world of law
I accept that the law can be entirely arbitrary and based on tiny technicalities, but it seems like Dell's in the wrong here to me.
Note that I'm not arguing about the spirit of the actions, but merely about whether Mozilla actually has a case here
Lawyer goes to mozilla.com, clicks Download. “By the plaintiff’s interpretation, as they have distributed the product to me, I now have an installed Firefox. Let’s go to the Start Menu and attempt to run it. Wait, hmm, I see no menu icons. Let’s look on the filesystem. Hmm, no folder. Oh, I see, there’s this additional step beyond distribution that I have to take to be able to use the product. What’s that additional step called? Installation. What do we call it when someone does something for us so that we don’t have to do it? A Service. Thank you, Your Hono(u)r (this is the UK after all, though it’d be M’Lord).”
Might be dick-ish (subjectively). But the Mozilla claims that it’s clearly not allowed by their license or trademark (which implies no association), and the repetition of same by the article (and by numerous in the peanut gallery online) does not make it so - Dell’s response is correct.
Dell also has a program for large enough IT departments where they'll use a buyer-provided disk image at the factory so machines can be deployed right out of the box.
