When I try to autofill with 1Password X at the login page above, the user name gets filled in, but the password field is left blank, which makes ML give an annoying error message covering everything up. I recently switched from Roboform, which worked fine on this website login. I see old posts on this forum about this issue, but no resolution of the problem (and the ML website has probably changed since then anyway). This happens for me on Win 10, 64-bit, with either Firefox and Chrome, latest versions.
