Comment 4 for bug 41179

Now that the Login Manager rewrite has landed on trunk for Firefox 3, writing a module to implement this support should be much easier. Basically, someone needs to write a component implementing the nsILoginManagerStorage interfaces, and that component would interact with the Gnome Keyring as needed.

This interface is described here: http://mxr.mozilla.org/seamonkey/source/toolkit/components/passwordmgr/public/nsILoginManagerStorage.idl

This task isn't currently on my to-do list, but I'd be happy to help explain the Login Manager interaction if someone wants to take a shot at this.
