Issue

The bitwarden extension does not load/appears blank when I open it in Firefox Private Browsing.

Details

This is a known issue with Firefox that Mozilla is unwilling to fix.

It is due to the popup being unable to communicate with the background page during private mode. Mozilla claims that inter-window communication should not be allowed in private mode.

Workaround
