Based on an outdated version of Firefox. Has trouble rendering most websites. Can also crash more.

Useful as a fallback and for testing things.

- SeaMonkey is Free and Open Source


Lighter on resources, had UI we were used to in old Firefox(version 3.x), some features like webRTC might be missing.
