1PasswordX extension will not open in window after Windows 10 18362 update

Good morning,

I just completed a Windows 10 update to 18362. I deleted and reinstalled 1Password X extension and rebooted the computer. When I clicked on the 1passordx icon in Firefox it does not appear in the normal pop up window, just a black window screen. Must be a trick I do not know. Ideas ?

Note: 1Password app on computer works just fine.

1Password Version: 7.3.684
Extension Version: 1.15.7
OS Version: Windows 10 V. 18362
Sync Type: 1Password Cloud


  • Correction to my post- Should have read "blank" screen instead of "black" screen

  • OK, read other posts and figured it out ...no need to reply
