Looks like NS 6.23 is based on Mozilla 0.9.4, not the 1.0 release.  Browsers.lib
classify both Mozilla and Netscape as "mozilla"...

NS7pr1 works fine (based on mozilla 1.0rc2).

It looks like the easiest thing in the UA string to check would either be the
data on the gecko release (ie gecko/20020611 in mozilla 1.0 vs gecko/20020508)
or the revision string (ie rv:1.0.0 in mozilla 1.0 vs rv:0.9.4.1 in ns6.23)

Is it worth differentiating between NS6 and other gecko based "mozilla" browsers
in horde/lib/Browser.php?
