## 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
If you are looking to auto-fill usernames and passwords while in Firefox Private Browsing, please visit [https://help.bitwarden.com/article/auto-fill-firefox-private-mode](/article/auto-fill-firefox-private-mode/#workaround).
