I've got a router which I access with 192.168.2.1
1Password always asks to save the password. I don't want it to save it.
I select from the little gear wheel to tell 1password not to ask about this web site.
But it always asks anyway.
Please try adding the address to the exceptions list in Preferences > Browser, below the 'Automatically ask to Save new Logins' option. This should ensure that 1Password doesn't ask you anymore. :)
