Thank you for that.

It is unfortunate that the AMD web page that linked to the download
for the package that depended on that package, di not include a link
to the package, with some information like "the package needs this
package to be installed, which can be downloaded form..."

I am well aware that Ubuntu is not Debian, although, from what I
understand, it may still be derived from, and, based on Debian.

As I had said, the Seamonkey package for Ubuntu, installed and runs
okay on Debian 7, and is the only source that I found, of a .deb
package for Seamonkey, so as to allow Seamonkey to be installed using
a Debian package manager, such as (I think it is) gdebi.

No, by "the other", I meant the Acer V3-772G, with the nVidia GT720M
(I think it is) graphics adaptor.
