How to remove mozilla properly?

[Vinicius]

Hello,

I would like to remove the following mozilla's packages:
mozilla-1.7.2-0.2.0, mozilla-chat-1.7.2-0.2.0, mozilla-mail-1.7.2-0.2.0,
mozilla-nspr-1.7.2-0.2.0 and mozilla-nss-1.7.2-0.2.0, but the command
"rpm -ev ..." shows:

rpm -ev mozilla-1.7.2-0.2.0 mozilla-chat-1.7.2-0.2.0
mozilla-mail-1.7.2-0.2.0 mozilla-nspr-1.7.2-0.2.0
mozilla-nss-1.7.2-0.2.0
erro: Failed dependencies:

        libssl3.so(NSS_3.2) is needed by (installed) gaim-0.82-0.FC2

Can I ignore this dependencies?

I would like to install the mozilla 1.7.3 (through
mozilla-i686-pc-linux-gnu-1.7.3-full-installer.tar.gz), this is why I
want to remove the mozilla 1.7.2.

TIA, Vinicius.
