What it does
SeaMonkey combines a maintained browser with mail and other internet tools, including a Data Manager for cookies, permissions, passwords and settings.
SeaMonkey's privacy use case is controlling stored browser information within its integrated suite. The official feature page describes a Data Manager covering cookies, permissions, passwords and preferences, alongside popup blocking. That is useful if you already prefer the suite's combined browser and mail workflow.
It has its own maintained releases rather than being a current Firefox channel. Check the browser and add-on compatibility required for the task before adopting it, especially where a website assumes the latest mainstream browser interface.
