The URLs are based on history which really doesn't matter at this point.
This could potentially change.

ATF installs XULRunner two ways, automatically downloaded using updated
manager and in ATF's platform specific "All-in-one" zip files.
1. Update manager
The basic requirement when installing ATF by update manager was to only
download the version of XULRunner for the platform. As I remember I
couldn't figure out a way to have one feature and not get all versions of
XULRunner downloaded. XULRunner for all three platforms supported today is
33 MB in size. We already have request for a 64 bit linux build which
would increase the by another 8-10 meg. I'm not a feature/update manager
expert, so there may be a way around this problem when using only one
feature.
2. "All-in-one"
One of the comments that ATF received was that the download size (eclipse,
wtp, and dependences) was too big. Working with the WTP and other eclipse
team changes were made that allows us to create an "All-In-One" package
for each platform with only the functionality needed by Web Developers (no
JDT, PDE, etc.). Packaging all platform versions of XULRunner in each "All
in One" would significantly increase the size of the download. Any
XULRunner feature layout would need to allow ATF to package only the
platform version of XULRunner needed and not show any errors in the
"Manage Configuration" wizard when all the versions of not there.
I'm not a feature expert, so there may be a way around my concerns when
just having one XULRunner feature.

This was done so a person can use ATF with an installed version of
XULRunner and not use the version packaged in a plugin. This allowed the
person to install a version of ATF without XULRunner. We probably need to
relook at the requirement. It may be possible to handle the problem using
the "optional" option on the feature.

I will add this to the agenda for the next public status call.
