List of previously generated passwords

I recently reset my password for a website using 1Password's generator in the Chrome browser extension, but did not save the new login details. The website is not allowing me to recover password details and so at this point I have lost the ability to recover access to the account. Contrary to advice I have found in these forums, I have not been able to view the generated password history by hovering over the 'generate' option while on the site's login page. Is there an easier way to view all passwords previously generated and filled into forms using the browser extension? Otherwise I'm completely locked out of my account for good.
