I'm stuck on the "The 1Password helper must be running for the extension to work properly" screen. With the same setup on Windows 8 I didn't have any trouble.
I've tried Chrome (55.0.2883.87) and Firefox (51.0.1). I've tried the steps in the support article. I do not have a firewall problem, and can access local web servers without issue. In 1password.agent.log.txt (in the diagnostic report), there are a series of entries like this whenever I try to connect a web browser:
13:35:38 [ WARN] T1pAgent4: Denying connection from 127.0.0.1:65287. Invalid user token. 13:35:38 [ WARN] T1pAgent4: Denying connection from 127.0.0.1:65287 13:35:38 [ INFO] T1pAgent4: Disconnecting from 127.0.0.1:65287
I never got the authorisation prompt. Did I miss anything?
