Hello, it hard to guess where to start with investigation. Could you please answer following questions so I know where to focus?

[ol]- Is extension’s key icon visible in browser toolbar?

  • If so what happens once you click on it?[/ol]

If the extension icon is not visible in toolbar please check the extension is enabled in extensions settings:

  • click on 3 dots in top right corner of the browser
  • Settings panel will show up
  • Check if Passwords is not greyed out
  • If so click on Passwords to activate it → will become green
  • Extension icon should show up in browser’s toolbar

Please let me know if any of these hints helped to solve your problem.
