This is a simple port of the PwdHash extension for Firefox by Collin Jackson. It is a naive port meaning no functionality was altered. The only changes made were to the install.rdf and chrome.manifest files in order to make it compatible with Songbird. There will undoubtedly be issues and bugs but the basic functionality is there. For a proper port, please lobby the original author to make PwdHash fully compatible with Songbird.
