K-Meleon
Homepage
OS: Windows 95/NT 4.0 or never
Open Source: Yes
Description: A Mozilla based browser designed for improved performance, response to user input and integration on Windows when compared to Firefox. K-Meleon sadly isn't as customisable as Firefox though and many extensions and all themes don't work with it.

Camino
Homepage
OS: Mac OSX 10.3 or newer
Open Source: Yes
Description: Similar to K-Meleon, Camino is a Mozilla based browser which aims for improved integration and speed on a particular OS - in this case Mac OSX. Like, K-Meleon, Camino sadly isn't as customisable as Firefox though and many extensions and all themes don't work with it. It does have an array of its own extensions though specifically designed for it.

Flock
Homepage
OS: Windows 98 or better, Mac OSX 10.2 or better, Linux
Open Source: Yes
Description: Flock is based on Firefox and is designed for integration with popular social networking sites such as Facebook, MySpace, YouTube, PhotoBucket e.c.t. Due to its Firefox roots, most Firefox extensions work with it, and many extensions designed exclusively for Flock work with Firefox. Themes are a different matter, however, and many of them are incompatible or only have partial functionality.

Mozilla Sunbird
Homepage
OS: Windows 98 or better, Mac OSX 10.2 or better, Linux
Open Source: Yes
Description: Sunbird is a powerful calendering and organisation program. Similar to its big brothers, Thunderbird and Firefox, it's open source and provides add-ons and themes for customisability.
