SyncServer is a Firefox sync server written in Perl.

This syncserver implements the syncserver user API and storage API as an fcgi application. It is entirely written in Perl.
Netscape Security Wrapper manages the loading of NPAPI (Netscape Plugin API) plugins and applies simple policy decisions. The intention is to allow administrators to deploy deprecated, unreliable, or unsafe third party plugins while minimizing the security exposure. Safari, Google Chrome, Firefox, and other NPAPI-compatible browsers are supported on OS X and Linux. Use cases include: restricting plugins to certain domains, restricting the use of deprecated plugins to known outliers, allowing internal corporate workflows which use insecure or deprecated plugins without exposing the plugin to the hostile Internet, and allowing multiple outdated plugin versions (e.g., Java) to co-exist for use in whitelisted, trusted enterprise tools.
UserAgent Theme Switcher is a simple plugin that lets you change the theme to be displayed according to the detected browser.

It is ideal for displaying themes ready for Opera Mobile, Internet Explorer Mobile, iPhone, Android, etc.

Arora is a simple cross-platform Web browser whose feature list includes things like "History" and "Bookmarks". It has a small code base. It was originally created as a demo for Qt to help test the QtWebKit component and find API issues and bugs before the release. A very old version can still be found in Qt's source code in the demo/browser directory. Arora works on Linux, OS X, Windows, FreeBSD, and embedded Linux using Qt Embedded, and works anywhere else Qt does.
GWTruts is an easy-to-use framework for using GWT with MVC and dependecy injection. It virtually divides a GWT module into view, controller, and validation sections similar to traditional MVC Web frameworks like Apache Struts. It also provides a dependency injection mechanism similar to Spring, which you can use to customize your controllers and views. It provides a page decorator where you can define mappings between a URL and a group of controllers/views and sections of the HTML files.
