Welcome to 1Password keeps appearing in my Browerq

I do clear cache but rarely, and it is not related to the appearance of the Window in Safari
I never clear Safari's history

and as a matter of fact, I received the email to view your posting and click on view to open to 1Password forum page and that bothering 1password for safari webpage appeared

why would the extension in Safari quit or Needed to restart, this is new and useless, if the extension does not work I will reinstall it period.
