kwallet integration for firefox

 Iceweasel and Icedove stores its passwords internally, optionally
 protected by a master password. KDE has its own password manager
 called KWallet.
 .
 KWallet stores every password in the KDE system, and protects access
 by a master password. With this extension you are able to use KWallet
 instead of the default Iceweasel/Icedove password manager. It allows
 tighter integration of Iceweasel/Icedove inside KDE.
