I use 1password extension with Firefox (v92.0). It has been working great. Whenever I require it I'd just press the keyboard shortcut and a window pops out (in the centre of screen) prompting to enter my password of my Ubuntu login -- lets call this authentication box. If it does this, everything should be fine. I'd put my PC (not laptop) into suspend mode and return to it normally.
However, there have been a few occasions now when I have to unlock 1password extension, the 1password app launched and prompted me for my 1password password. This is not the same authentication box. The main application opens.
From this point on, if I put my machine to suspend and logs back in, the above-mentioned authentication box appears frozen at the top-left of my screen. I cannot click it off -- hovering the mouse of the Cancel button highlights the button but clicking it does nothing. I can, however, click any where within the popup window and interactive with any objects or links below it even though the popup is opaque. See screenshot..
Notice the cancel button? If the Visual Code Studio icon below it is on the same row as the password field, clicking it will launch the VSCode application.
The point here is that this popup window cannot be moved, removed, resized, etc. As the popup sits above all layers, it is obstructing everything else below it. The only thing I can do to is to log off Ubuntu and back in.
