SeaMonkey might not be quite as obscure as some of the other browsers on the list, but it's certainly not a household name. SeaMonkey is actually more than just a browser; it's a browser, email client, feed reader, HTML editor, IRC chat, and more. SeaMonkey shares much of the same code as does Firefox and Thunderbird and features: Sync, session restore, themes, feed detection, smart location bar, popup blocker, safe mode, find as you type, and much more. Though you might find the UI a bit out of date, SeaMonkey is a good choice if you're looking for an all-in-one solution. SeaMonkey is available for Windows, Linux, and Mac.
