I learned some time back that one could make gnome capture midori passwords through:
I tried it by then, but I didn't like because gnome-keyring was capturing all passwords.
I don't use desktop environment, so I was using in my ~/.xinitrc:
eval $(gnome-keyring-daemon --start --components=pkcs11,secrets)
As I use ssh-agent + keychain, I just removed the ssh agent...
However that was capturing every password, from firefox, thunderbird, etc. Although one could refuse to capture them, it was uncomfortable to me, so I decided NOT to use gnomekeyring just for midori.
The thought I have, is that perhaps there's a way to specify gnome-keyring to only pay attention to midori passwords, and nothing else. Though I don't see that in its options through the gnome-keyring-daemon man page.
If there's a way, please let me know...
