I cannot get the production 1Password X extension (1.7.3) working in my Firefox 60.0.1 installation on macOS 10.13.5
Clicking the 1Password X icon in my tool bar takes me to this URL: moz-extension://cd83df11-5c1b-5a4a-b35c-cb98198ef652/app/app.html#/page/welcome but displays a blank page.
I have uninstalled and re-installed the extension several times.
1Password Version: Not Provided
Extension Version: 1.7.3
OS Version: macOS 10.13.5
Sync Type: 1Password X (Family)
