I created the folder manually and tried re-installing the extension (and went through the process of granting it access to other programs etc.) but again it didn’t help.įinally I copied this file from a working machine and that helped. In my case neither file nor folder ( NativeMessagingHosts) was present. Looks like the following file is needed for browser integration: ~/Library/Application Support/Mozilla/NativeMessagingHosts/. And thanks to this GitHub thread I finally cracked it.

I was in a particularly adamant mood so persistend in trying to find a solution. Enter 2FA code if needed (I did not disable 2FA for testing). Finally I gave up and moved on… until today. WebLogin to the Bitwarden Firefox extension using Login with device (not master password). I’ve reinstalled the Bitwarden, the extension, Firefox, rebooted… all the usual stuff, but nothing’s helped. On this (macOS) when I ask the browser extension (Firefox) to use biometrics it keeps complaining that Browser integration is not enabled. Bitwarden browser integration works fine on all my machines, except one.
