Turn off Chrome redirect behavior?

I'm glad I was able to clarify things :)

There was no behavior that allowed you to left click without loading the saved URL (unless you're referring to very old versions of 1Password).

As for step #3 - you need to open the 1Password extension on the top right corner of your browser's toolbar. No right-click, just normal left-click on 1Password's extension icon on the top right corner of your toolbar to open it, then grab the username field with your mouse, drag it over onto the username field on the website. Repeat this for the password field separately. It is easy and quick because 1Password's window will remain open so no need to right-click or copy-paste or anything.

This doesn't work from any menu within the page, only via the 1Password extension's window on the top right corner of your browser.
