    Firefox is a fair replacement for SeaMonkey's web browsing component. For a full replacement of the suite, additional software (such as Thunderbird) is required.

    Thunderbird vs SeaMonkey opinions
    Some users think Thunderbird is a great alternative to SeaMonkey, some don't.

    SeaMonkey is a full internet suite, while Thunderbird is just an email/scheduler. Thunderbird does not have a web browser (although it integrates well with Firefox), for instance.

    There are very few projects that cover as much ground in a single application as Seamonkey.
