Description:
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.
