I get no notification on the desktop and after a few seconds it errors out.
I have tried uninstalling bitwarden app and reinstalling it, both the browser extension and the desktop app.
Unchecking the “allow browser integration”, logging out, logging back into the desktop app and re-checking it and then logging into the browser extension app but nothing working so far.
I’ve been having the same issue recently and I couldn’t find any information on it besides this post. I’m glad I’m not the only one having the same issue.
What is your Bitwarden browser extension version on Firefox?
Can you unlock the desktop app with Touch ID? → If not, that has to work first, before you can set it up for the browser extension. (–> see also here: Unlock With Biometrics | Bitwarden)
What I found when setting up biometric unlock: do it step by step… if something doesn’t work, close all apps and browsers, open everything again and continue where you left off.
If the folder is not there, you can just create it yourself. However, it needs to contain the manifest file (com.8bit.bitwarden.json). If the manifest is absent, you could try copying it from the NativeMessagingHosts subfolder from another browser (one in which biometrics work). Or you could go through the biometrics setup process, which should allow the Desktop app to place the necessary manifest file in the NativeMessagingHosts subfolder.
