I'd like this extension to work in Edge :)

I received the error message in the Issue Title

Hello, the error you are getting is because it's not enough to just install Browserpass, every browser has to also be specifically configured - however unfortunately we don't have a configuration yet for the Edge 🙂 If you like to try, you can try to find it or reverse engineer it, and submit a PR once you succeed - look at paths in Makefile for other Chromium derivatives, maybe you will just succeed in guessing 😉 If not you can at least feel free to share your findings in this issue, so that other community members can jump in and also try to help.

@maximbaz I've managed to get this working with the user command by placing the json file in "$(XDG_CONFIG_HOME)/microsoft-edge/NativeMessagingHosts/$(APP_ID).json.

The system-wide command is a bit less straight forward.

The directory structure for Edge is sufficiently different to the point I'm not so sure how to proceed.

I was looking for a similar directory to /etc/opt/chrome/ for Edge, but Edge doesn't appear to install into that path. The nearest I can find for Edge is /opt/microsoft/msedge/. Then, I took a chance and placed the native-messaging-hosts folder in that directory, but to no effect.

Further:

• I'm not 100% sure what the policies functionality is or does
• I don't have a Mac so I can't attest to the Darwin file paths and instructions

I'd be happy to open a PR with modifications that add support for Linux via the hosts-edge-user step, but it would be incomplete support for the browser.

How would you prefer I proceed at this point?

PR #122 opened for discussion

[max-baz]

Thanks for the investigation and for the PR 👍 Will leave the comments there.

I'm not 100% sure what the policies functionality is or does

It auto-installs browser extension, so that a user doesn't have to get it from Web Store. In the browser extension list, such extension would look a bit different, with "Uninstall" button disabled as it's impossible to remove such extension directly from the browser. You could say, abusing a bit a browser feature of enforcing corporate policies in order to improve user experience of getting the extension to work 🙂

Thank you for explaining. Fair enough! It's a nice touch for convenience :)
