   Thunderbird vs SeaMonkey Comments

   Negative comment by Guest · Apr 21, 2017

   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.

   Thunderbird is an email client, while seamonkey is a web browser and are two completely unrelated things.

   Thunderbird is an email client, not a web browser.
