I think this happened before in an older update where the CTRL+\ shortcut would not fill in fields or bring up the pop-up menu for 1Password 4. The addon is still usable but it is a good deal more tedious. It also seems like the prompts for new account generation do not show up, so all logins would have to be entered manually when making a new account, which is less than optimal. If this could be fixed again this would be very appreciated.
