FireBreath is a cross-platform plugin architecture, targeting NPAPI browsers on Windows, Mac OS X, and Linux (Gecko/Firefox, Google Chrome, Apple Safari, Opera) and ActiveX Control hosts, including all versions of Microsoft Internet Explorer. It is designed to make it easier to get started than even doing an NPAPI plugin by hand. A Python-based "fbgen" tool generates a template skeleton and makes it possible to have a functioning browser plugin up and running in 20 minutes.
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which use insecure or deprecated plugins without exposing the plugin to the hostile Internet, and allowing multiple outdated plugin versions (e.g., Java) to co-exist for use in whitelisted, trusted enterprise tools.
