do not close add-on pop-up on focus loss

[jficz]

Current Status The addon popup window (the one that show when the addon icon in toolbar is clicked) is closed/hidden immediately when the browser window loses focus. Tested on Firefox (LibreWolf) and Chromium (Brave).

Feature Description The window should optionally only close on explicit action such as:

• clicking outside the window (but inside the browser window)
• pasting creds
• copying generated password
• pressing ESC or clicking a close button
• etc.

Additional context Closing the window on focus loss breaks many useful use-cases, for example:

• entering the master password using local pass-dmenu or other similar password operators
• copy-pasting multiple things to/from the window
• re-typing the password manually to sites/places which are disconnected from the browser window (like RDP sessions)
• any other workflow which requires focus switch

This behavior can not be controlled by the extension.
