SeaMonkey Community

Development of the SeaMonkey Internet Application suite software wouldn't be possible without the vibrant community of developers and users that form the SeaMonkey Project.

Planet Mozilla

Planet Mozilla is a central hub for Mozilla-related weblogs and features all kinds of news and developer statements from all around our big community, of which the SeaMonkey project is only one part.

Reporting a Bug

Any change that is made to SeaMonkey requires a so-called "bug" to be filed in Mozilla's bug tracking system Bugzilla. A "bug" is basically a change request and uniquely identified by a numerical ID. A bug can be about a defect in the software, a feature request or an idea of how to improve exiting functionality.

Anyone can file a bug. All you need is a Bugzilla account, which is free. But since the goal is to get bugs fixed, it is vital that bug reports are as precise as possible. Please read the Bug Writing Guidelines before you file your first bug.
