fixup! BB 4234: Use the Firefox Update Process for Base Browser.

BB 44668: Allow to replace detailsURL with unsupportedURL.

We perform unsupported detection locally, rather than with a
server-side logic, that is what Mozilla does.
So, we send unsupported users to the details of the actual update,
rather than sending them to a page with details of why they are
unsupported.
With this patch, we can distinguish those cases, and send user to a
more appropriate page when needed.
