This is a known issue specific only to Firefox. You will see a message indicating so when you try to open the Bitwarden popup window in a private window. We have discussed the problem with Mozilla, however, they seem unable to fix it so that extensions like Bitwarden can function entirely in private mode. There are currently 3 workarounds for auto-filling a login while in Firefox's private browsing mode: 1. Use the right-click context menu: 1. Navigate to the website's login page while browsing in a private window. 2. Right click the page. A context menu will appear. 3. Select **Bitwarden** → **Auto-fill** and then pick your login. 2. Copy/paste your login credentials by accessing your Vault in the popup from a regular, non-private browsing window. 3. Use the keyboard shortcut for auto-filling a login (CTRL + SHIFT + L by default on Windows, CMD + SHIFT + L by default on Mac) ## References - GitHub discussion: - Firefox Bugzilla report:
