Well, generally /usr/lib/mozilla is a symbolic link to the current
version of Mozilla.  If you did the "ls -ld /usr/lib/mozilla*", you
may have seen this at the end of one of the lines:

	/usr/lib/mozilla -> mozilla-1.4.2

If so, you don't need to change anything as putting the link in
mozilla-1.4.2/plugins is the same thing as mozilla/plugins.  Symbolic
links are aliases, meaning that "/usr/lib/mozilla" is just another name
for "/usr/lib/mozilla-1.4.2".

Mozilla is run as "/usr/lib/mozilla/mozilla", so having
"/usr/lib/mozilla" point at the current version makes it easy to upgrade
versions, but still be able to go back to a previous version if the new
one doesn't work.  This is done by installing in a new
/usr/lib/mozilla-(version)" directory and changing the symbolic link.
If you don't like it, change the symbolic link back to the previous
version.

For example, here's what I have (cleaned up to fit the display):

[root at prophead root]# ls -ld /usr/lib/mozilla*
/usr/lib/mozilla -> mozilla-1.6
/usr/lib/mozilla-1.2.1
/usr/lib/mozilla-1.4
/usr/lib/mozilla-1.5
/usr/lib/mozilla-1.6

So, I have versions of Mozilla from 1.2.1 through 1.6, but the active
one is 1.6.

Symbolic links are special files.  "rm" will delete them.
