Hi Sergei,
Firefox behaves differently. It asks for a master password for the site, whichis empty in our case. But when given empty password, it gives a messagebox which says "signature is needed". If I say "ok", it says "can not parse signature".
I have similar problems with FF 1.0.7 on my old 0.9.2.1 installation - so I guess its a Firefox issue
